Yeah it does look like that, however he is deficating and his sides aren't hard. Normally he's pretty symmetrical. Thats why I believe its fluid retention. He's also eating and his stool looks normal so i guess that rules out a bacterial/fungal infection. At i least I hope so because before I saw him acting strange, I put him in a tank with my other whites. Prehaps I should have quaratined for a longer period of time. Also if its pathogenic, wouldn't a frog be drawn to the water to soak MORE instead of LESS?
