He just died It all happened so fast. One minute he was his old self, then he was just gone. I have no idea what happened.

I am concerned for his tank-mates, however--especially the grey tree frog I had in with him--it was a temporary solution until I had the financial means to separate them. The Grey Tree Frog is exhibiting the same thinness (actually, I had observed it in him before), but he is extremely energetic and feeding and defecating properly. I have him quarantined, but I don't know what is going on
