Health Fish Tip #5 – Keep aggression under control: If you have an aggressive tank such as an African cichlid tank then there will be aggression and territorial conflict. This is normal and probably healthy for the fish because it is natural. However if you notice a fish that is too aggressive or one that seems to be getting picked on by all of the fish in the tank, then you need to find a way to resolve the problem. Sometimes merely rearranging the tank can change the tank dynamic and perhaps give a “picked on” fish some new hiding spaces. If rearranging the tank does not work, then consider removing the problem fish from the tank and placing it in a different tank or perhaps trading it in to the local fish store. Stressed fish are prone to disease and once a stressed fish becomes diseased it is more likely other healthy fish in the tank will contract the disease from the stressed fish.

The goal of following these healthy fish tips is to avoid having to treat the fish after they become sick. Happy fish keeping!
