Hello all!
I have 5 serpae (red minor) tetras, and they all seem to be getting sick. For several months now I have had fish with this visible illness in at least one of the serpaes at any time, and I have had to replace a couple. This sickness causes dark (grayish) slightly-raised bumps, marks, and scab-like tissue to appear on various parts of the fish. I have noticed that it slowly spreads, usually starting from the head/face of the fish only as dark marks. Eventually the fish's entire body becomes discolored to a significantly darker shade. The funny thing is, the serpae tetras are the only fish that have it; the neons and zebras are fine. I have no idea what this is! I have considered parasites, but I can't be sure. Does anyone have a possible diagnosis? Maybe a similar-sounding disease? Suggestions for treatment?
Thanks in advance!
