I just got home from work and went to turn on the light in Ty's tank (5 gallon hex). I didn't see him swimming or under the plant. I looked between the HOB filter and the back of the tank. Nothing. I looked over the stand at the floor and there he was. The tank has a cover on it but apparently he jumped out throught the 1.5" square hole that you knock out for the heater to go through. How in the world he did that I don't know. He was completely dried out so he must have done it shortly after we fed him and went to work.
