I had a lot, and I mean A LOT of Geckos when I was lil' Kev1144...Day Geckos, Crocodile Geckos, Leopard, Fat Tailed, Tokay Geckos
First off, I don't know why Pet Stores even sell Tokay Geckos...you might as well buy a Piraha, cut your finger and stick it in the tank, because you will be less likely to be bit than sticking your hand into the tank of a Tokay Gecko. Mine personally sucked and it was 5 years of misery, but he did look nice.
That aside, I loved my 2 Leopard Geckos...I read someone saying they are small...when they aren't really at all. Both my Geckos were great and would actually eat hand fed and fall asleep in my hand. The Day Gecko was ok, fast moving, and the Fat Tailed Gecko was a really good pet as well. The Crocodile Gecko was like Grey Wolf in Metal Gear Solid. I'd put the crickets in, you would see flashes of brown and blood flying everywhere, but you wouldn't really see the actual Gecko, just utter carnage. I never even attempted to hold him. But from someone that's owned a lot of Geckos I would recommend a Leopard Gecko.
