Hi,
I have three FBT's and I have had them for about three years now.
A couple weeks ago one of my FBT's escaped the tank. Luckily, my dad found him and put him back in the tank.
Since then, I put a heavy book on the top of the lid, but he somehow escaped again. So I duck taped the lid, and put three heavy books on the top of the lid instead of one. After that it didn't happen again, but my frogs have been climbing the walls and sometimes hanging from the top lid and just hanging out up there , like they hate getting wet or staying near the bottom. The one that escapes is the smallest and he is one-eyed, but he somehow always squeezes out! Is this normal? or something I should be worried about?

- Thanks!
