I post far too much in this part of the board, but I worry about my little buddy.
Today I noticed he has one little white string of sorts hanging out of his gills. He's not breathing heavy, he's just sort of hanging out around the bottom of the tank, but for him that's pretty normal. His gills don't look pushed out or anything, just that little string is hanging there. I read that it could be columnaris but I didn't really find much of a treatment for that.
I also just noticed that he has one scale that looks whiter than the others. I'm going home this weekend, so I won't be able to watch him on Saturday, but I'll be back by Sunday and if anything has changed I'll update.
As a side note- is it ok if his dorsal fin curls a little? It's been split a little at the ends for quite some time and the little split pieces curl up a bit. [the bottom of his anal fin does the same thing...]
Again, sorry for asking so many questions, but I can't really find any answers online.
