Hey everyone. I know the title is confusing, but let me explain. I woke up this morning and found one of my 4 inch thin-bar floating around on one side and then the other. I've seen this before with other fish that have died. There's 2 things that confuse me. 1. When I see the fish doing this I know that it will die, but how come my other fish are healthy? Also, #2 is what the title is about. When I saw my dying thin=bar this morning, I thought it was one of my stable ones. It wasn't. The dying one would always hide in the corner and be the "rare" black color. As it floats around dying, the colors are very stable. The yellow is bright and the stripes are very dark. The colors are sharper than my most stable dat. I thought dats become stable when they feel secure and comfortable? How come mine has become stable as its dying. Any feedback is appreciated, the Doc.
