The Domino Damselfish is among the easiest of all marine fish to care for. Being very hardy it is suitable for the beginner saltwater hobbyist. The only things they really need are a few places to hide in rockwork and to be fed 3 times a day. Even though they are quite durable, they still can fall ill if exposed to poor water conditions for too long.Even though they are gregarious as juveniles and can be kept in a group, they become very aggressive as they age. Adults will attack any other damselfish as well as other tankmates that are not equally aggressive. These fish need 55 gallons or more and should be kept singly, unless the tank is very large with many hiding places for shelter. Doing normal water changes, feeding them a variety of foods several times a day, and having the proper tank mates are necessary to keep this damselfish.
