I have 3 clownfish (I ordered 2 but received 3) that have been getting getting along swimmingly for the past 6 months (pun intended). All of a sudden this week, 2 of them turn on the other. I got him into a hospital tank alone without any other fish. His fins are tore-up. What is the best and quickest way to get him healed? There is a quick video below showing the injuries. Once healed, I'll find him a new home.
