I recently moved my FBT into a 45 gallon tank due to his old 10 gallon one breaking, and I wanted to know if there's anything else that could live with him in there such as reptiles, amphibians or aquatic things (not fish). Something that climbs to inhabit the top part of the tank would be ideal.

I got him at Petsmart when I was 8 (now 16) and they said the ones they sell weren't poisonous, although I don't know if what they say can be trusted.

I am planning on getting more FBTs though.
