Thats rather funny......i'm a leo owner whose been looking at maybe getting a chameleon LOL. I haven't done extensive reasearch yet, still trying to get my gecko room organized (did a move from one room to another). There are many people around who can help you out as well as many good caresheets online.
I myself, have 14 geckos (11 leos, 3 crested geckos). They are all in tanks ranging from 10 &15 (quarentine tanks) to 20 and 40 gallons. I use ceramic tiles as substrate, feed mealworms, butterworms and superworms from bowls in the evenings, use under tank heaters for heat, occationally using lamps, mainly during the winter. Each gecko has a humid hide (tupperware, sour cream, margerine container) with either a hole in the side or top, filled with vermiculite. Top hole works best to keep the vermiculite in the container hehe. I have a dish of calcium in each tank as well as logs, rocks, caves, artifical plants, and hammocks for decor.
I hope this helps you out a bit. By all means ask if you have specific questions....there are so many wonderful people on here i'm sure you'll get the help you need
