Tips
for Green Iguanas
Green iguanas (Iguana iguana), decorated with a row of impressive spikes
along their backs, a spiked dewlap, massive heads, and patterned, colored
scales, live up to 12 years and can grow to a length of six feet.
Their natural range runs from Mexico southward to include almost
two thirds of South America, and a number of islands in both the Atlantic
and Pacific.
As pets, these creatures demand some extra care, especially in
their housing and diet. Compared to some other lizards, Green Iguanas demand
a little extra care, but these impressive reptiles can make themselves
more than worth the trouble and provide you with pride in accomplishment,
too.
Remember:
-
Care takes 45 minutes to an hour, every day.
-
Iguanas cannot be house trained.
-
They can scratch if handled carelessly.
-
To be healthy and happy, pet iguanas need conditions similar to those in
their wild life.
Housing
-
Cages: for a hatchling, a large glass aquarium of 25-55 gallons, and for
adults a cage 6x6x4 feet should be adequate. (Avoid cages with clear class,
screen, or hardware cloth near the floor.)
-
The cage floor lining should be nontoxic and easy to replace, such as a
mix of one part potting soil to three parts beach sand. (Not small gravel.)
-
Provide non-toxic houseplants and safe plastic plants for basking, hiding,
foraging, drinking, and elimination. Iguanas prefer to rest and bask on
strong branches that slope between 10 and 30 degrees.
-
Waste material must be removed from the cage regularly. You may want to
feed your animal outside its cage to help keep the cage clean.
-
Iguanas enjoy a light water misting. Humidity in their cages should stay
around 70 to 90%.
-
Include a small water bowl for drinking, and a larger one for soaking.
For larger animals, a once-a-month bathtub soak is better.
Light
Iguanas need consistent periods of light and dark to regulate their body's
daily activity. Twelve hours of light and dark each day is ideal.
Ultraviolet light helps them produce vitamin D, a critical nutrient,
by activating a substance in their skin and converting it to the vitamin.
Iguanas need full spectrum light, either from basking in direct sunlight
unfiltered by glass, or from a good full spectrum artificial light, for
several hours daily. (Remember to change your UV light bulb every 6 months,
and keep it within 15 inches of your pet, to keep it most effective.)
Iguanas are cold blooded, and don't generate their own body heat.
During the day make sure that one end of the cage is heated to 95 degrees
F, and provide a cool spot of about 70 degrees at the other end. At night,
the temperature can drop by 10 to 12 degrees. Intense heat and light can
burn an iguana's skin. Use a thermometer to ensure that the warmest part
of the cage under the lamp gets no warmer than 90-95 degrees.
Feeding
-
Schedule daily feedings consistently.
-
Food must include a balanced variety of nutrients, including protein, fat,
carbohydrates, and minerals and vitamins, especially calcium. At times
of seasonal change, offer the animal a selection of foods.
-
Calcium can be offered in a number of different forms, such as oyster shell,
calcium sulfate blocks, bone meal, or cuttlebone, available at any pet
store. Hatchlings up to 24 inches long should get 1/4 teaspoon of calcium
powder sprinkled on their food each day, 1/2 teaspoon for larger animals.
-
The safest way to make sure an iguana gets enough Vitamin D is to let it
produce it's own by basking in sunlight. (Note: commercial pet foods are
sometimes already fortified with vitamin D, and could actually induce an
overdose, so use them carefully.)
-
One good source of easily digested protein is boiled egg white. One teaspoon
a day seems to be a good guideline. Adults shouldn't receive any egg white.
Legumes such as alfalfa and bean sprouts are excellent vegetable sources
of protein.
-
Iguanas may ignore water bowls. Lightly misting the inside of their cage
and the rim of their water bowl with clean tap water will usually stimulate
them to drink.
Food preparation
-
Prepare feed for iguanas fresh every morning.
-
Always allow an iguana to warm up by basking while its meal is being prepared,
especially its morning meal.
-
How a food feels is important to iguanas. Diced or chunked food can be
difficult to eat, and they might refuse it entirely. Shredding the same
food into short, thin lengths can make it much more acceptable. Later in
life, as the animal develops larger and more powerful jaws, it may prefer
its food in larger chunks.

A Typical Meal
Kale, spinach, apple, carrot, and broccoli shredded together in a food
processor, with alfalfa sprouts and bean sprouts then mixed in, and then
topped with crumbled boiled egg white or chow. Half a cup of this mix will
be more than enough for a hatchling. Finally, this "salad" is top dressed
with calcium powder.
The basic mix can be made more colorful and tasty with moderate
amounts of small berries, diced bananas, melon, tomato, corn kernels, etc.
Buying an Iguana
Select a pet that is bright green in color, active, and basking; avoid
those that are dark, thin, or sluggish. Watching a group of iguanas being
fed is a good way to tell which ones are feeling well.
Breeding
Young imported animals are widely available and inexpensive, so there's
not much incentive to breed them domestically, but it can be fascinating.
If that sounds interesting to you, we can help with advice and information.
Iguanas are clean and elegant animals that bring some of nature's wildness
into our homes, and caring for them can be a deeply rewarding experience.

Ball
Pythons (Python regius)
by Ashley Legore
INTRODUCTION
Ball pythons are a docile snake originating from west Africa to central
Africa. The ball python acquired its name because of its defensive behavior
of rolling up in ball. Hatchling ball pythons range in length from 10-17
inches and adults from 3-5 feet. Ball pythons are a great family snake
and are easily handled by supervised children, but due to their reluctance
to eat regularly they are not recommended for beginners unless the specimen
is a proven eater.
PICKING OUT A BALL PYTHON
The best ball python to pick out is a captive bred juvenile. If you must
pick an older specimen pick out the smallest in length of the group. Most
ball pythons in the pet trade are wild caught specimens, they often times
make poor captives unless set up properly, and you have to have a lot of
patience. Upon physical exam the snake should have a strong grip, good
muscle tone, and the ribs or spine should not be protruding. Eyes should
be clean and clear. Nose and mouth should be free of mucus and bubbles.
There should be no evidence of trauma to the scales and all should be intact.
Abnormal skin from past sheds should not be retained. Check the vent and
make sure no smeared diarrhea is present. Commonly, ball pythons will have
ticks or mites, and unless you are willing to deal with the presence of
these parasites, or you have other snakes, you should pass over these specimens.
HOUSING
Juvenile ball pythons can be housed in a 10 gallon aquarium. Adult snakes
can be housed in a 30 gallon aquarium, larger is preferred. All aquariums
or cages should be escape proof: ball pythons are excellent escape artists.
The most important item for these snakes is the hide box. Ball pythons
are very private and need a great deal of security to be cared for properly.
Ball pythons require a great deal of privacy because they are a nocturnal
snake (active at night). There should be a hide box located at either end
of the cage, one on the hot side and one on the cool side. Hide boxes for
ball pythons need to have the entrance at the top, an inverted flower pot
with a hole cut in the bottom works best. They live in burrows and hang
their heads out to catch prey, pulling the prey into the burrow to eat
it. In order to keep them feeding readily and happy you must recreate this
behavior in captivity. Substrate should consist of newspaper pellets, astroturf,
aspen or pine bedding.
LIGHTING AND HEATING
Ball pythons require no light and prefer no light shining in their environment.
Light shining in the hide box or on the snake causes stress and acclimation
problems. Heating is achieved by using a heating pad or heating tape under
the cage. The daytime temperature should be 80-85 degrees with a basking
area (covered by a hide box) reaching 90 degrees. The nighttime temperature
should drop to 75-80 degrees.
FEEDING
Refusal to feed is the problem most associated with ball pythons. If you
picked a healthy specimen it will be able to fast with no ill effects.
Records of ball pythons fasting for up to a year are not uncommon, so do
not panic. Rules for feeding ball pythons are as follows:
-
Set up your cage exactly as noted above.
-
Allow your pet to acclimate for 2-4 weeks prior to feeding.
-
Make sure the temperature is right.
-
Introduce all food items at night, the darker the room the better, the
more privacy the better.
-
A fuzzy mouse to juvenile or an adult mouse to an adult snake. Wild caught
specimens will not eat dead prey, they need to be taught this after they
are feeding regularly.
If the snake still does not eat try these tricks. Cover the entire cage
with a sheet or blanket to ensure the most privacy. Try a gerbil, they
are the native rodent of Africa and easily recognized as prey. Test a fecal
on your snake at the vet to check for internal parasites, this should also
be done for a snake that is eating. Brown bag method, put the prey item
in a paper bag with the snake overnight, use dead prey to be sure your
snake will not get chewed on. Only force feed your snake if absolutely
necessary; consult your vet first.

BEARDED
DRAGONS (Pogona vitticeps)
by Ashley Legore
INTRODUCTION
Bearded dragons are becoming increasingly popular as pets because they
are the tamest of all the lizards. They have outgoing personalities and
numerous interesting social behaviors (such as head bobbing, tail curling,
and arm waving) They make an excellent addition to any collection, and
are easily handled by supervised children.
PICKING OUT A BEARDED DRAGON
Most all bearded dragons in the pet trade are captive bred, so they are
usually healthy. Look for a clear eyed individual with a "well filled out"
belly. Make sure the dragon is alert and eats readily. Upon physical exam
make sure all toes are intact, and that no scales or tail tips are missing
(these will not grow back). Avoid animals with rubbed noses or damage to
lips or mouth.
HOUSING
Young hatchlings should be kept in a bare cage; a 10 gallon aquarium works
well. The cage substrate ( floor material) should consist of newspaper
or paper towel, and one branch or rock should be placed in the middle of
the cage for basking. When the lizard grows to at least 4 inches from head
to end of tail more cage furniture and substrate can be added. Small hatchlings
require a lot of food to survive: a lot of cage furniture and substrate
causes problems with finding the food items. For adults, cages should be
large. Same-sex housing is not recommended due to territorial behavior.
An adult pair should be housed in no smaller than a 55 gallon aquarium,
and larger would be preferable. Bearded dragons enjoy plenty of branches
and rocks for basking. Substrate for adults should consist of newspaper
pellets, astroturf (with no frayed edges), or a sand and potting soil mixture.
I prefer newspaper pellets they are clean and absorbent. A screen lid is
required, and a shallow water dish will be appreciated for bathing.
LIGHTING
Lighting for bearded dragons is very important. Being a desert species,
they require a lot of heat and UV light in order to ensure optimal health.
Temperatures should range between 85-90 degrees with a basking spot of
100 degrees. Temperatures should go down to 75-80 degrees at night. Heat
is best obtained by using an incandescent heat lamp or ceramic heat fixture
focusing on 1/2 of the cage. During the winter it also helps to have a
heating pad under the hot side of the cage for extra heat. The most important
item for bearded dragons is UV light. UV light can only be achieved with
a fluorescent light bulb. This light should be rested above the cage, within
15 inches of the lizards. The lights should be on a 12 hour light cycle:
12 hours on and 12 hours off.
FEEDING
Feeding bearded dragons is easy due to their vigorous appetites. They will
try to eat anything put in the cage, including branches, twigs, frayed
astroturf and substrate. Hatchlings should eat daily. Finely chopped greens
should be offered daily and animal products should be added every other
day. For sub adults and adults, greens and veggies should be offered every
2-3 days and animal products every 3-4 days. Animal products include crickets,
waxworms, meal worms, and pinkie mice. Dust the food items with calcium/vitamin
powder 2 times weekly. Bearded dragons should be misted daily to ensure
proper hydration.

Box
Turtles
by Ashley Legore
INTRODUCTION
The box turtle genus, Terrapene, includes 4 species and 11 races of currently
recognized subspecies. They range over most of the U.S. east of the Rockies
down to Mexico. Box turtles are common first time pets for reptile owners,
but need special requirements. They should not be a beginner's pet.
PICKING OUT A BOX TURTLE
Most all box turtles in the pet trade are wild caught, so a fecal sample
should be checked right after purchase. Look for a turtle that is clear
eyed and active. The skin should be clear, with no abrasions or retained
abnormal skin. The shell should be well formed and hard, with no evidence
of trauma. All toes should be intact. The ear membrane should be flush
with no bulges, and the mouth and nose should be free of bubbles or mucus.
HOUSING
The housing for box turtles should be large; the floor space should be
4 foot square per 1 adult specimen. The sides can be low (about 1-2 feet
high). No top is needed for the enclosure, as they will rarely climb. Substrate
should consist of newspaper pellet litter, a sand/potting soil mixture
or pine/aspen bedding. Turtles need plenty of substrate for traction, as
well as for burrowing. A shallow pan for water is required: this should
be cleaned daily and the damp substrate around it removed and replaced.
Outdoor pens can be used during the summer months. Make sure when building
pens to sink the sides to prevent digging out, and make sure there are
no predators in the area (dogs, raccoons, opossums, etc.) that will prey
on the turtles.
LIGHTING
Heat can be achieved with an incandescent heat lamp over a corner of the
cage to provide a basking spot. UV light is also required and can only
be achieved with a fluorescent UV bulb, which should be suspended over
the cage within 15 inches. These lights should be on a 12 hour light cycle,
12
hours on and 12 hours off.
WINTER CARE
Possibly the greatest long term challenge to many box turtle keepers is
their turtles' biological need to spend a significant portion of the cold
months inactive. As the leaf colors change outside, the turtles' appetites
start shutting down. The trick, when keeping box turtles indoors, is to
provide cold enough conditions to allow them to truly stay inactive. Below
50 degrees is needed to remain "asleep." Stop feeding the turtles at least
10 days prior to hibernation; all food needs to be evacuated from their
guts. Soak them so they're fully hydrated. Put the turtles in a plastic
shoe or sweater box with holes poked in it for air. Cover them with moist
leaves or shredded newspaper. Put the box in a darkened location where
the temperature doesn't rise above the low 50's. Throughout winter, keep
the substrate moist and soak the turtles every couple of weeks.
FEEDING
Box turtles should be fed every 1-2 days. They eat a variety of things
including, greens, veggies, fruit, dandelion greens and flowers, earthworms,
meal worms, wax worms, slugs, crickets, and high quality dog food. A varied
diet is best to ensure optimum nutrition.

Colubrid
Snakes
by Ashley Legore
INTRODUCTION
The snake family Colubridae contains the largest numbers of snake species
worldwide. They range in size up to 10 feet in length, and occupy a large
variety of environments. Colubrid snakes generally are easy to care for
and make nice pets.
PICKING OUT A COLUBRID SNAKE
Look for a snake who is alert , and has clear eyes and no abnormal retained
skin from past sheds. Ask if it has eaten lately and if you can see it
eat. Find out if the snake is captive bred or wild caught. The snake should
have a nice rounded body with no ribs protruding.
HOUSING AND LIGHTING
Depending on the size of the snake, the perimeter of the cage should be
twice as long as the entire length of the snake. The cage should have many
hiding places and some branches for climbing; a large water bowl for soaking
will also be appreciated. Substrate should consist of newspaper pellets,
aspen bedding or pine shavings. Heat should be provided by using an incandescent
heat lamp or a heating pad on half of the cage.
Temperature should not exceed 88 degrees in the day, and at night
should be between 70-75 degrees. The light should be on a 12 hour light
cycle, except for in the winter, when it should be a 9-10 hour light cycle.
A tight fitting cage lid is extremely important is: colubrid snakes are
great escape artists.
FEEDING
Most all colubrids snakes eat mice or rats, depending on the size of the
snake. Garter snakes will also take gold fish, frogs, salamanders, and
earthworms, but will readily change over to pinkie mice.

Day
Geckos
by Ashley Legore
INTRODUCTION
There are approximately 57 species and subspecies of Day Geckos, all of
which belong to the genus Phelsuma, in the family Gekkonidae. These colorful
lizards make excellent additions to a collection, but remember to look,
not touch. They make excellent terrarium subjects, with interesting habits.
PICKING OUT A DAY GECKO
Look for a bright, alert gecko that eats readily. Make sure all its toes
are intact, its nose and lips should be undamaged, and it should have no
patches of left-over skin from sheds. The base of its tail should be thick,
its ribs should not be protruding, and its eyes should be large and clear.
HOUSING
Housing Day Geckos is very easy. A 20 gallon aquarium works well for a
pair of small geckos, a 30 gallon aquarium works great for a larger species.
They are arboreal lizards, so a terrarium that has height rather than floor
space is preferred. The cage furniture should be easy to clean but provide
a lot of hiding and climbing places. Strong leaf tropical plants can also
be utilized. Substrate can consist of newspaper pellets or moss (moss should
be changed regularly). A tight fitting lid should also be used: geckos
will readily escape.
LIGHTING AND HEATING
Day Geckos require UV light provided by a fluorescent tube light ( UV light
can only be achieved with a fluorescent bulb). Heat is best achieved with
an incandescent heat bulb. The temperature range should be between 7O-90
degrees, with slight temperature drops between 8-10 degrees at night..
The heat should be consistent. Lights should be on a l2 hour light cycle:
12 hours on and 12 hours off.
WATER AND HUMIDITY
Day Geckos require a constant supply of fresh water. A drip system works
well, and should be placed over some leaves for easy drinking. Humidity
should range between 40-80%, so misting twice daily is recommended.
FEEDING
Day Geckos are primarily insectivores. They will accept fruit flavored
baby food, fruit juices, and nectar. They will lick off of fruits such
as bananas, apples, and berries. Crickets, waxworms, meal worms, and wingless
fruit flies should be fed, but wild caught insects should be avoided with
these species. Dust all prey items with a vitamin powder that contains
a calcium/phosphorus ratio of 1:2 to 2:1. Prey items should be given 2-4
times a week.

Leopard
Geckos (eublepharis maculaius)
by Ashley Legore and Dan Ranes
INTRODUCTION
Whether you have just caught the reptile "bug" or are an advanced hobbyist,
don't overlook this surian gem! This ideal pet takes little space, has
simple food requirements, and comes in designer colors. A maximum size
of 8 inches makes it easy for supervised children to enjoy this hardy lizard
as well.
>PICKING OUT A LEOPARD GECKO
Look for an active and alert specimen, with a fat tail (approximately
3/4 the thickness of its neck) and bright coloration. Avoid lizards that
don't open their eyes when touched, don't eat readily, or have old skin
stuck to their toes.
HOUSING
Since leopard geckos are terrestrial lizards they can easily be kept in
a glass or plastic cage that is at least 6 inches high and has a floor
space of 10 inches by 10 inches. A 10 gallon aquarium works very well for
an adult lizard. Line the cage with newspaper or newspaper pellet litter
(never use fine grain sand: leopard geckos become impacted easily) and
put on a screen top. Provide a shallow bowl of water. A hide box is also
appreciated and will aid in shedding. Leopard geckos eat their shed skins
as well. A hide box consists of a 6 inch plastic container with a hole
cut in the lid large enough for the lizard to pass through easily. Fill
the box with moist moss or sterile potting soil, and mist the inside of
the box daily (the gecko will also enjoy a misting)
LIGHTING
The temperature range for these lizards should be as high as 82-88 degrees
during the day and as low as 67 degrees at night. Heating is best achieved
by an incandescent heat lamp on 1/2 of the cage. Usually a 40-60 watt bulb
for a 10 gallon tank is sufficient. UV light is also essential, UV light
can only be achieved by a fluorescent bulb. There should be a 12 hour light
cycle of both the heat and UV light: 12 hours on 12 hours off.
FEEDING
Leopard geckos eat crickets, meal worms, and occasionally a large adult
can handle a pinkie mouse. Dust the food with calcium powder twice weekly
and make sure your lizard is heated to the optimum temperature before feeding.

Monitor
Lizards
Ashley Legore
INTRODUCTION
The two most common species of monitors in the pet trade are the Savannah
Monitor (Varanus exanthematicus) and the Nile Monitor (Varanus niloticus).
This care sheet applies to both species. Savannah Monitors are from west
Africa and range in length from 2-3 feet. They are generally a placid and
easily handled pet. Nile Monitors are from eastern and southern Africa
and grow to between 4-5 feet (with the occasional larger specimen): they
are generally an aggressive, ill tempered pet but with lots of attention
can be "tame."
PICKING OUT A MONITOR
Look for a monitor that is active and eats readily. The specimen should
be of good weight but not obese (Savannahs have a tendency to get obese).
All toes should be intact and no abnormal skin should be retained from
previous sheds. The mouth should be clean and free of mucus or bubbles,
and the nose should be clean and free of sores or scabs. Eyes should be
clear, and skin should show no signs of trauma or sores. The base of a
healthy monitor's tail should be fat, at least 3/4 the thickness of the
body.
HOUSING
With monitors the "bigger is better" rule is best when looking at cage
size. A good rule to follow is, the length of the cage should be at least
twice the length of the lizard and the width at least as wide as the length
of the lizard. Monitors should be housed separately unless you are in the
process of breeding. Nile monitors are arboreal lizards ( tree climbing)
and require a tall cage. Plenty of branches are required for climbing.
Savannah monitors are terrestrial and require some rocks and a low branch
for cage furniture. Cages should be strong and sturdy, because monitors
will escape readily. Cages are best made out of plywood and plexiglass
with a wire mesh roof. Wire mesh is not recommended for the sides, since
some species will rub their noses raw on the wire. A hide box is appreciated
for privacy. Substrates that work best are newspaper, newspaper pellet
litter, astroturf, linoleum, and aspen or pine bedding.
LIGHTING
Daytime temperatures should range from 82-90 degrees with a basking spot
of 95-100 degrees. This is best achieved with an incandescent heat lamp
or ceramic heat bulb shining on 1/2 of the cage. UV light is also required
and is very important. (Remember: UV light can only be achieved with a
fluorescent UV bulb.) The lights should be on a 12 hour light cycle, 12
hours on and 12 hours off. Nighttime temperatures should drop down to 70-75
degrees.
FEEDING
Monitors are carnivorous lizards and will eat just about any meat item
offered. Food items include mice, rats, rabbits (for large species), crickets,
meal worms, all other insects, birds, fish, eggs, and other reptiles and
amphibians. A varied diet is the best way to ensure the best nutrition.
Clean, fresh water should be available at all times, in a container large
enough for the lizard to bathe in. Daily misting of the monitor is also
required to raise humidity and aid in skin management.

Ashley Legore and Dan Ranes
INTRODUCTION
With impressive features and great climbing abilities, the water dragons
make exciting pets. They require a large cage, and some specimens are hard
to keep captive. With the right set up and following their easy eating
requirements, though, they make a nice addition to a collection.
PICKING OUT A WATER DRAGON
When purchasing a water dragon find out if the specimen was wild caught
or captive bred (generally, captive bred water dragons make the best pets).
If wild caught, ask how long it has been in captivity. Pick a dragon that
is active and alert, eats readily, has no external parasites, and has no
old shedding skin still attached. Look at the housing: the cage should
be well maintained and sanitary. This helps keep the numbers of bacteria
and parasites down. The lizard should be free of wounds, all toes and toenails
should be intact, nostrils should be dry and free of crust, the mouth should
have no mucus or bubbles around the lips, color should be good for the
specific species, and weight should be good and evenly distributed with
ribs only slightly visible. Water dragons' noses and nostrils should be
intact: they have a bad habit of rubbing their noses off on their cage.
HOUSING
Being a large lizard, with males up to 36 inches (including the tail) and
females only slightly smaller, water dragons need a spacious environment.
They are arboreal lizards (they climb trees, and spend the majority of
their time in trees). They are also excellent swimmers, often sinking to
the bottom of their water bowl and staying under water without breathing
for up to an hour. Their cage should be very large, at least a 75 gallon
aquarium per 1 adult pair. Cages should not be made with wire mesh due
to the nose rubbing problem these lizards experience. A large bowl of water
or a watering system, deep and big enough for swimming, is required. Water
should be clean and fresh. High humidity is essential for these lizards
but good ventilation is also required. Plenty of branches for climbing
should also be available, as well as lots of foliage. These lizards like
to have foliage or a hide box in the cage to reduce stress. This also helps
with the nose rubbing problem.
LIGHTING
Daytime temperature should be 85-87 degrees with a nighttime low dropping
as low as 75 degrees. This heat gradient is easily achieved by using an
incandescent heat lamp on 1/2 of the cage. UV light is essential for these
lizards (the only way to get proper UV light is with a fluorescent UV light
bulb). The heat lamp and the UV light should be on a 12 hour light cycle:
12 hours on and 12 hours off.
FEEDING
Water dragons are mainly carnivores, but will accept some vegetable or
fruit matter occasionally. Finely chopped fruits and veggies should be
offered 1-2 times weekly. Meat items should be offered daily to hatchlings
and young adults and 3-4 times weekly to adults. Prey items include crickets,
meal worms, earthworms, goldfish, quail chicks, and mice. The food items
should be dusted with a carnivore specific vitamin powder once weekly.
Make sure your lizard is heated to its optimum temperature prior to feeding.

Turtles
by Ashley Legore
INTRODUCTION
The keeping of turtles has long been a popular hobby. Until a few years
ago, many species of turtles were readily available in pet stores. Today,
however, so many state, federal, and international regulations are involved
with collecting, importation and sale of water turtles that many shops
don't carry them at all. The needs of water turtles can be complex and
misunderstood, and meeting these needs is especially important if the specimen
is going to be kept healthy and in captivity for a long period of time.
PICKING OUT A WATER TURTLE
First of all, look at the environment that the turtle is kept in. It should
be clean and properly lighted (noted later in this care sheet). No feces
or uneaten food should be floating in the water. The turtle's eyes should
be clear and open wide, the ear membrane should lie flat and have no bulges.
There should be no cracks or abrasions on the shell. All toes should be
intact and skin should look clean and free of fungus or film. The turtle
should eat readily, and the mouth should be intact and free of mucus or
lumps.
HOUSING
Adequate housing will, of course be determined by the size and quantity
of turtles you are keeping. With water turtles it is better to err on the
side of excess than to have too little space. For instance, an adult Red
Eared Slider should be kept in nothing smaller than a 30-40 gallon tank.
Larger ponds, cattle troughs or child wading pools work well also. Not
only will the turtle need water, but it will need a haulout area for basking:
a flat rock or floating platform or log works well. Clean water is of great
importance so, however you set up your turtle's enclosure, make sure it
will be easily cleaned and drained of water. A submersible water filter
is also helpful.
LIGHTING AND HEAT
Water turtles require two types of light. First is a basking light consisting
of an incandescent heat light hanging over a basking spot. The second is
UV light, provided by a fluorescent UV light bulb suspended over the cage
(within 15 inches). The lights should be on a 9-12 hour light cycle, on
and off. During the winter months a submersible water heater should be
used to keep the water at a comfortable temperature. Basking temperatures
should be between 84-94 degrees and water temperature should be between
72-80 degrees.
FEEDING
Food items consist of goldfish, crickets, meal worms, earthworms, beef
heart, commercial turtle food, and greens. All uneaten food should be removed
from the cage within an hour to prevent contaminating the water. Water
turtles should be fed every 1 or 2 days. Food sources should be dusted
with vitamin/calcium powder once or twice weekly.
