I have had a couple of dwarf gourami's in the 20 gal for about 3 months and will move the the 29gal within a month. This morning I noticed the blue is bloated, he is a little pale, and his scales are sticking out where he is swollen, but is acting fine. None of the other fish have anything wrong. Ammonia +nitrite=0, nitrate 30, temp 82, ph 7.5, kh 5, gh 12, phos 3. Anyone know whats up?
