Here to ask a question on behalf of my fiancee who has two fire bellied newts in her kindergarten classroom. Tonight, one of them was *looking* a little bit bloated, and it was swimming just below the water surface but either couldn't go to the bottom or didn't want to. The other newt in the same tank was swimming crawling around the bottom as seems normal.
Is this a problem, and if so, is it common? Any advice would be appreciated.
