Hey guys, I need help and quickly! I got Shaun T about 6 months ago and I noticed a bit of fin rot about a week ago, so I started doing water changes every 1-2 days, pretty much as often as possible. 4 days ago I noticed that overnight it became quite severe with a large portion of his dorsal fin missing. That is when I took him out of his 2.5 gal and into a QT tank with 2 tsp of aquarium salt per gal. Just yesterday I woke up to find that he now has gotten pretty dark in color around his head and a white spot had formed also on his head. Its now twice the size it was and spreading to the other side of his head. I don't know if its columnaris or not because it doesn't look fuzzy at all it looks more like the scales are just dieing. I've also noticed on the rotten fin area there's little red dots appearing, at first there was just one and now I'm seeing a couple. also some of the fin is becoming translucent I'm wondering if that's regrowth or degradation of what was there. please help! I'm not sure if I should up the AS to 3 tsps or get some medicine. I'm in panic mode, I don't want anything bad to happen to him
He was also looking a little bit bloated and didn't poo for two days, finally last night he passed a giant turd. I did start feeding him one more pellet once I got him in a QT cos I was hoping it would encourage fin re-growth. I fasted him today just to be safe. I don't know if I made matters worse or not. I hope not :S
