What should I do if my fish is injured by another fish?
Typically, a fish when they get injured, the only way they get injured is by another fish attacking him or biting him or what have you. That'll typically happen during feeding time. What you have to determine is was it a one time occurrence? Kind of a warning shot across the battle if you will, or do you have a dominant fish that is taking down a sub-dominant fish. If that's the case it will not stop. That fish will take that fish out and I mean completely out. They're wild animals; they think like wild animals, they don't operate any other way. There's a sick fish or a weak fish, the strongest of the fish is going to see an opportunity for food, and it's going to take the fish out. So you got to take a determination how severe it is. And if that's the case, usually the indicator risk: will the lesser fish get to eat when you feed? And if it does not get to eat one of those two fish has to go because ultimately its going to end up in the demise of the weaker fish almost guaranteed.
