ARE YOU SURE YOU WANT A SNAPPER?
Snapping turtles are fascinating animals, and captives are relatively hardy with proper care. However, the large size, long life, and aggressive nature of this species deserve serious consideration.
Size: The carapace length of common snappers frequently exceeds one foot with a record length of 18 ½ inches (Pritchard). The average adult weight is thirty pounds, but 40-60 pounders are not uncommon (Dillon). Snappers grow fast! That 2-inch baby you brought home to a ten-gallon aquarium can be 4 inches in one year and 8 inches in two. It will eventually require either a pond setting or a gigantic aquarium (more than a hundred gallons).
Messiness: Snappers are both voracious eaters and highly aquatic. This combination equals frequent water changes! The best filtration cannot keep up with smelly snapper wastes. You must be prepared to do complete water changes at least once a week if not more often.
Aesthetics: If you want a beautiful tank landscaped with plants, you do not want a snapper! Your little charge will rearrange the tank to his or her liking, uprooting plants and pushing everything including rocks and the filter into new positions. Snapper tanks must be kept simple. Expense: The initial investment for any turtle amounts to several hundred dollars for a tank, filter, heater, UVB lighting, and a basking light. Larger tanks and equipment for your eventual "behemoth" will cost much more.
Aggressiveness: Yes, it's true that snappers are more docile in their aquatic environment than on land. They sit quietly and give you long soulful stares - hungry stares!!! Snappers will eat anything including your fingers! They charge their food, and your digits can easily be mistaken for worms in a feeding frenzy. You cannot mix them with other turtles including other snappers. Even small snappers can cause serious harm to each other. They will also attempt to eat all the other inhabitants of your prized outdoor pond, including ducks and ornamental fish.
Longevity: The life span of the common snapper has been estimated at 30-40 years (Dillon). Are you prepared to commit one third to one half of your life to your friend? What if you move? If you are thinking you can just release your turtle in a few years, remember that most states still permit the harvesting of snappers. You wouldn't want your buddy to end up in a can of soup! And zoos are "full up" with unwanted snappers and other reptiles. Most are no longer accepting ex-pets.
Please think twice and thrice before acquiring a snapper. It is cruel to take home that cute baby on an impulse if you cannot provide permanent quarters. Snappers are living, breathing beings and not playthings. Please award them the compassion they deserve.
BASIC CARE FOR SNAPPING TURTLES
By Jean Adamson
You have decided to take the plunge! I hope the following care sheet will get you started:
Tank Setups
Glass Aquariums: You may temporarily keep your snapper in a water-filled plastic container, but you will eventually need a glass aquarium for your indoor accommodations. Some snapping turtles kept in close confinement develop sores on their bottom shells from constant abrasion with plastic, rocks, or other rough surfaces. The affected areas will initially look more orange than the surrounding color and will progress to pinhead-sized holes in the shell. Sores that do not heal with corrective husbandry should be seen by a vet.
In addition, glass enclosures allow your friend to look out. Your baby snapper that wants to hide will soon turn into an intelligent, inquisitive juvenile that enjoys "watching the world go by." If you house other turtles in aquariums, try placing one end of your snapper's aquarium end-to-end with another turtle's tank, but provide a place for retreat and privacy at the other end.
Remember that your snapper is going to grow fast! A one-inch baby will become a 7-inch juvenile in two years with the proper diet. Buy the largest tank that you can presently afford. A rule of thumb is to provide ten gallons of water for each one inch of snapper shell length. Your ten-inch snapper is going to require a one hundred gallon tank. The tank should be long and wide rather than tall to provide more swimming area. Since a snapper will stay at the bottom of the tank most of the time, a tank with shorter walls will facilitate rays from your lighting source reaching your turtle. A 30 gallon "breeder' tank (12" high x 36" long x 18" wide) makes a good first choice for a small snapper.
Substrate/Covers: The author and some vets recommend a completely bare-bottom tank, at least for beginners. Snappers are messy, and you will have enough work changing all the water once a week without also doing gravel washes. You will not need gravel to anchor plants or decorations, because your snapper will uproot, rearrange, and eat everything in the tank, including the gravel! Do not place plastic plants, large marbles, or other decorative items in your snapper's tank if you do not want a snapper with a life-threatening intestinal impaction! Snappers in the wild bury themselves in mud at the bottom of marshes and lakes. This environment may be simulated in an outside pond, but the author hasn't experimented with soft substrates in indoor setups.
An older snapper may eventually be able to crawl out of the tank. You may need to buy a hood or screen cover or construct your own.
Hiding/Basking: Your snapper, especially a baby, should be provided with a hiding place at one end of the aquarium. The author recommends, however, that you do not build a cave with rocks or pile up rocks in the tank. Your snapper is powerful and may bring the whole structure down, pinning your turtle underneath. A good hiding place can be fashioned from a small, plastic kitty litter pan. Cut out one end of the pan, turn it upside down at the end of the tank, and put a very large rock on top to hold it in place. Another option the author has used in an 18-inch wide tank is a 17-inch wide Rubbermaid kitchen stool placed widthwise with a rock on top. The snapper feels secure under the stool but can still see out.
Wild snappers usually stay submerged at the bottom of water bodies, but some will bask by either floating at the surface or "hauling out" onto logs. You can experiment with a basking spot by wedging a smooth piece of wood between the aquarium walls and angling it up out of the water. Fasten a clamp light fixture available at hardware stores to the tank rim with a 60 watt bulb (reptile or incandescent) a foot over the basking spot.
Water Depth/Temperature: WATER DEPTH IS MOST IMPORTANT! Snappers spend most of their time resting on the bottom and extending their long necks up to get breaths just above the water surface as needed. The depth should be at least a bit deeper than the turtle is wide to allow for swimming and righting the body if turned over, but shallow enough to allow for breathing from a resting position. If your snapper is forced to swim to breathe, it may die from the energy expenditure. A hatchling should be observed to see whether or not it can lift its head out to breathe and the setup changed to include a dry slope if it is having trouble.
Snapping turtles need a slightly cooler range of water temperatures than that prescribed for some other species. They will feed eagerly at 68 degrees F or above but become uncomfortable with water temperatures in excess of 77 degrees F (Highfield). Submersible glass tube heaters or other electrical appliances that might easily be broken by snappers should not be used in their enclosures due to the risk of electrocution. The author heats her snapper's tank with a combination of warm room temperatures and a basking lamp. Do not leave a thermometer in your snapper's tank!
Filtration: Buy the strongest filtration system you can afford. A Duetto 100 submersible filter may work for a hatchling in ten to twenty gallons of water but will not keep up with wastes as your snapper grows. Reasonable persons may disagree as to what constitutes effective filtering. The subject is a paper onto itself. You must experiment with what works for you, knowing that the bottom line is keeping the water clean. Large external canister filters provide strong filtration, but the author's snapper continually dislodged and bit the tubing. You may be more creative and find a way around this dilemma. The author presently has great success using a Fluval 4 submersible filter, hand-siphoning observable solid wastes with a turkey baster, feeding her snapper in a separate tub, and one-week water changes. Effective filtration will depend upon whether you choose to use a substrate or not, the size of the turtle and its tank, the size of the filter, the filter media, how you feed your turtle, and other factors
Lighting: If your snapper does not have access to natural lighting in an outdoor (pond) setup, you should provide a reasonable facsimile for the UVB component. Do not place your tank in a window for several reasons. The water in your tank may overheat and kill your snapper. The glass in the window and the tank will filter out the beneficial UVB component of the sunlight. The sunlight may cause algae to grow in your aquarium.
You can buy a hood that holds UVB tube lights to place over your tank or you can make one. If a hood you buy contains glass or plastic strips that protect the tube lights, you will have to remove the strips which filter out the UVB light. Other options include hanging a shoplight fixture with the tube lights over your tank or setting one or more strip light fixtures with the tube lights on a screen cover. The consensus recently seems to be that Reptisun 5.0 tube lights made by Zoomed work well. They lose their effectiveness over time and need to be replaced every 6 months to 1 yea
