4 weeks ago I rescued an entire tank full of cichlids that look like they were swimming in mud. I have one starry night cichlid the seems to be breathing hard and hanging out near the top of the tank. Water parameters are good. I don't see ick on any of the fish but With the conditions they were living in before I'm afraid they may have parasites or other things going on specific to cichlids. Can anyone recommend what meds I should use. I think I need to treat them all to be safe and I have zero experience with cichlids.
