Mediterranean, Turkish, or House gecko. The scientific name (to break down the barriers of common names which vary) is Hemidactylus turcicus turcicus. They have been introduced into Florida, Texas, and isolated colonies have been found as far North as the Southern regions of North Carolina. Pet stores usually carry a 100% plastic enclosure called a Kritter Keeper. I keep baby Hemidactylus in the 1/2 gallon size (which is the 2nd size up). The one Gallons which are the 3rd size should be fine into adult hood for a single of that species. A five gallon (4th size) would be more comfortable and allows enough room for a small potted plant, such as a bromeliad or potho.. A few large flat pieces of bark placed vertically will be appreciated for hiding and climbing purposes. For a substrate (bedding) you can make a mixture of Sphagnum peat moss, potting soil (the fertilizer and Styrolite-free type), and cypress mulch (never cedar, the oils are bad for the respiratory tract of most reptiles). A commercial substrate called Jungle Mix works well. Spanish moss adds a natural feel and also retains humidity. You will need some calcium with vitamin D3 (D3 helps them absorb calcium; Repcal is good) because their growing bones can easily be deformed while "soft." In the wild they usually get this from powdered oyster shells and other hard egg shells. I don’t believe mealworms are good for this species, especially hatchlings and juveniles. They do not die from the minimal pressure of "chomping" from these geckos and can scratch and bite at the lining of their esophogus (heard tales of them eating through small lizard's stomachs, but I don't believe that is possible). Crickets are a good food source throughout life, and occasional waxworms when it gets larger will be good also. Do NOT feed any crickets larger than the geckos head. You do need a clean spray bottle, for they will get about 85% of their moisture from condensation on plants or the cage walls, the other approx. 15% from food. Mist the enclosure (wet all sides and slightly moisten the substrate) at morning and night, feed 3-4 appropriately sized crickets (about the same length and width of the geckos head) every other day for adults and every day for juveniles. Maintain a temperature of around 75-78. You can use a 25-35 watt black light placed over one end of enclosure. This is not necessary, but mainly for nighttime viewing, a humidity level of 65-80%, a hiding spot away from eyes (behind one of those bark pieces laying against the side is good, and some branches for additional perches for hunting. That should provide for a happy little gecko. If you collect hatchlings and juveniles remember they dehydrate faster, and lower temps and more frequent misting are necessary. They reach a total length of around 6-6.25 inches

(taking in consideration, the size of the tanks).the adults looks more marbled than the baby, will they get darker as they age?
