Hey All - Got a beautiful Queen Angel this weekend. It's very active and healthy and eats anything we put in the tank. When we got it, it had a orange/brown lump on its side. The original owner thought it must have gotten nicked when it was netted from her tank. We thought it would clear up in a couple of days. Four days later, the lump is the same or a little worse. We are starting to worry that it is a parasite rather than a cut. Any thoughts about possible causes and treatments?
