Aggression among fish, particularly marine species, is a problem that plagues both beginning and advanced aquarists. For example, you buy a new fish and add it to your apparently peaceful community tank and suddenly violence erupts. Long-term residents react aggressively toward a newly introduced fish, causing acclimation difficulties. This can lead to stress, disease and often the subsequent death of the new addition. The purpose of this article is to examine reef fish aggression and suggest techniques that will allow us to reduce conflict in our saltwater aquariums.
Aggressive fish and how to deal with fish aggression and bullying.
One of the most challenging aspects of keeping saltwater eels in the aquarium is their extremely aggressive temperament. Most large species of eels are predatory and will quickly devour any species of fish that they can fit in their mouth. Therefore eels should only be kept with large, moderately aggressive tank mates that are able to hold their own ground. Aquarists should also take care when handling an eel aquarium as they can often bite the hands of their keepers when scared or when in a feeding frenzy.

No matter what your skill level, to keep saltwater fish successfully requires providing and maintaining a properly set up aquarium. Many beginner saltwater fish are easy keepers in a 30-gallon aquarium, and there are a few that can be kept in a smaller 10 or 20-gallon tank. Once you have your aquarium up and running, take your time in selecting your fish. Start slowly, populate your tank with the correct number of hardy species, introduce peaceful fish first and add the aggressive fish last, and get the hang of maintaining the marine environment.
