Its a small UTH. I believe it is appropriatly sized for a 20g tank. The woman at work used it with her bearded dragons, and I don't believe she had a problem with it. I just wanted to make sure I didn't start using it and have it burn the geckos' bellies.

And I'm taking the gecko number down to one for now. I'll be ready to get one by the end of this month or beginning of April. I am not getting one from a petstore. I went to the Petsmart a few days ago and 2/4 of their baby geckos had lost thier tails and I understand that leopard geckos lose thier tails easily and they do grow back, but I'm wanting an already grown lizard with a tail. Possibly a male to start off with.

Are males particularly nippy? Or are leopard geckos even biters?
