actually im SUPER lucky, I have a peice of slate (I think its slate) leaned up against the front of the tank, and he has taken that as his/her spot. has tried some others, but thats the oen.I think its way cool looking. I saw it eat once, and that was when I put in some iguana food in there, I only do that like 2 times a week cuz I know its not best for the fish. but I dind't want to throw it away aand my iguana wouldn't eat it.
