My little guy is in a small Kritter Keeper with natural logs and fake plants. very shallow food and water dish and paper towel substrate.
He gets CGD changed every few days and 1/2 dozen crickets 2-3 times a month. He's only about 6 grams.
I have a 10 gallon all ready for him when he starts to show some more growth. In there I have Paper Towel substrate, thick (2" diameter) logs going across for climbing. 2 medium driftwood pieces on the ground to act as decoration as well as hiding spots, and fake plants.
My room/reptile room is between 73-76 degrees all day so I do not provide any heat for the Gecko.
When he is an adult I will probably upgrade him to a nice tall Exo-Terra enclosure.
