My DT male has been biting his tail after the most recent water change. I noticed this evening that the ragged edges of his fin have a red look to them, and now I am worried he is developing fin rot. This has happened literally in just a few days of him biting his tail. I am in the process of trying to cycle his tank, so I don't want to take him out, nor do I want to disrupt the cycle by putting a bunch of medications in there, but of course I will do anything I need to do to help Zen.
