Housing fat-tailed geckos is easy. Start with at least a 10-gallon terrarium or larger, depending on the number of geckos being housed. A 10-gallon tank will easily house one male and two females. A 20-gallon long tank can house one male and up to five females. Never house males together, as they are very territorial and tend to damage each other. Use coconut fiber or Reptibark for the substrate.
Provide a water bowl large enough for the geckos to get their heads in to drink, and give them two hides. Put one hide on the cool end and one on the hot end of the tank. More hides can be provided if desired, along with real or plastic plants or other décor. Each hide box should be large enough to hold all the geckos in the tank. Given that fat-tailed geckos require some humidity, place damp moss or similar material in one hide box to help keep the geckos hydrated. These “humidity chambers” help the geckos when shedding and also help to keep them cool when they need it.
Place a heat pad at the bottom of one end of the tank for heat (a heat lamp can also be used but tends to dry out the environment). The ambient temperature should be about 80 degrees with a hotspot of around 90 degrees. No additional lighting is required besides what’s in the room normally, because these geckos are nocturnal. DO NOT USE UV BULBS it can damage the geckos eyes. Lightly spray the tank every few days to maintain a humidity of about 40 to 50 percent. Spray the moss or other bedding in the hide boxes once a week or as needed to keep the hides moist. Add new damp material to avoid mold buildup every two to four weeks or as needed.
Fat-tailed geckos are insectivores. They will feed on crickets, mealworms, waxworms, Phoenix worms, and even very small pinky mice. Feed them daily to three times a week, as much as they will eat in one sitting. Dust the feeder insects with a calcium and multivitamin supplement every other feeding to ensure proper bone growth and D3 intake. Do not allow too many uneaten cricket to wander the cage, they can annoy and nibble on your gecko! try leaving out some cricket food to keep them occupied and gut loaded.
Fat-tailed geckos are being bred in increasing numbers now. You can still get fresh imports at a rather low price, but these usually arrive with regrown tails and can be rough-looking and a little beat up. To help preserve wild populations captive Breed is always the better option.
There are two standard wild morphs, one being banded and the other with a single white stripe running down its back. There are many exciting morphs bred in captivity now, the most common produced being “jungle,” with a pattern where the band on the body and tail are broken. It also comes in a striped version. There are amelanistic fat-tails with colors ranging from peach, orange, tangerine and red with gray or white backgrounds. Those, also, come in the striped pattern. Other new morphs include: aberrant, patternless, white outs and white sox. More new colors and morphs are bound to pop up in the very near future, making fat-tailed geckos one of the most versatile color morphs of just about any gecko, second only to the leopard gecko.
