Seems odd to me but I recently got this adult male and he wont use the hides but sits on top them.
He is a big boy and wont fit in the reptile basics large hide without it popping up off the ground(he did use it the first day for about an hour).Anyway I though it must be too small thats why he wouldnt use it..
So I got a kitty litter pan and made a hide for him and he still wont use it. He just lays all out in the open. Very friendly guy, so must have been handled alot by the previous owner. He was in a overheated 20 gallon before with two juvenile bps, which he was sitting on and squishing..Now he has a t8 all to himself but he is near the 4ft mark easy.I probed him myself and he is no doubt a male just a big one.
