Greetings O' Healers of Fish!
I have a 75 gallon FO
tank that has one 3 Spot Damsel, 4 Chromis, and 1 Gramma Basslet (the Basslet arrived yesterday). One of the Chromis has a serious injury where his tail starts. Simply put, parts of him are missing. I first started noticing symptoms about two days ago in the form of red spots near where his body ends and tail begins. I immeidately started treating the tank with Melaflix (7 tsp), but the fish's injuries only seem to be getting worse. I am not sure if this is a disease or the result of an overly aggressive fish. It can't be the Basslet since he arrived yesterday and this pre-dates his arrival. Aside from his injury, his behavior seems normal. That is to say, his breathing is not stressed and he continues to eat. So there you have it fellow fish doctors. What is your diagnosis? Thank you.
