HI y'all, I have a sick Ryukin he has been listless for the past couple days dividing his time between floating almost perpendicular near the surface, and sitting very still on the bottom. I have him in a 29g tank with a Sarassa I had lost one last week so it is just the two of them now. It was suggested that I put an air stone in the tank. The two perked up a little, but this evening I noticed some small black spots on the ryukin's head. I am at my wits end; I have done several water changes normally 20-30%.
Anybody have any ideas?
