I’m brand new to the hobby starting this past Nov. I’ve recently been battling a velvet outbreak in my tank after doing everything I could to prevent it, buying QT fish or observing for 30 days myself. Anyway, some of the fish appear to be doing great except the foxface tail is a little reddish and was wondering if it’s fine or if I should do something. I believe his fin got nipped for the gem in QT. This is a separate observation tank they are in now. Appreciate any help and advice. Observation tank.
