I recently got a new iguana that came with a 40g breeder (too small), well the tank has a 1" diameter hole cut in the bottom which I guess was for cleaning purposes but the iggy is no longer in such a small tank so now I have a spare tank that I want to use for fish. Can I fix this by getting a small square of glass and sealing it aroung the hole? I really want to use this as a growout for some catfish I'm planning on getting.
