So I have had my Vietnamese Blue(Klaus) for over a year now and this morning I was shocked to find him dead in the tank. He was very bloated and his tongue was sticking out. Honestly it kind of looked like he was blowing up from the inside out. Last night he was absolutely fine and ate his fair share of crickets. He was in a terrarium that has a waterfall feature but not so much water that he could drown in. there are 3 other frogs that live in there with him and i'm just concerned that they may get whatever Klaus had. one is a white's tree frog and 2 others are green tree frogs.
As a side note, he has always acted different from the other frogs that I have had (whites and greens) and has always liked to sit in the water. This morning I did find him in the water, and I do know that this could cause him to bloat, but not swell from the inside out like that. his whole mouth was open and it looked like he was about to burst. any help would be appreciated. I just want to know what happened and how I can prevent this from happening to my other frogs.
Thanks,
Mary
