At work, I have a Silver Dollar that's been there for two or three months now, he has what I believe is Black Spot Disease. From what I've read it's non life threatening, not contagious, and should go away on it's own. How long should it take (approximately) to disappear? Poor little guy looks like someone pricked with a pin over and over, and his fins are pretty torn. I always feel bad for the underdog and have a personal vendetta to helping the less fortunate critters :;dk...so I'm considering bringing him home for a while to fix him up. The only problem is the tank I can QT him in is only 10g..is this OK for a few weeks? Should I add any medications to help with the black spot? I can add him to my 55g afterwards until he gets better, all of my stock is small right now, so he shouldn't get beat on or anything. Keeping him permanently is probably not fair to him as I only have a 55g with no plans of upgrading for a few years. Should I/shouldn't I?
