Sergeant MajorFamily: PomacentridaeAbudefduf saxatilis
One of the Sergeant Major's natural habitats are the beds of Turtle Grass (Thalassia), found in the inshore zones of the Florida Keys!
Abundant throughout the atlantic ocean in many regions, the Sergeant Major is a damselfish that is readily available, inexpensive, and hardy. Though they are cute little fish when purchased as juveniles, they can turn into very territorial adults. Make sure you have plenty of room and lots of decor for them, so they can claim a space of their own.

Habitat: Natural geographic location: Atlantic Ocean: Rhode Island, USA to Uruguay in the western Atlantic. They are abundant on Caribbean reefs; around islands of the mid-Atlantic, Cape Verde, and along the tropical coast of western Africa south to Angola. Sergeant Major (Abudefduf saxatilis) is strictly an Atlantic species. The point map data in the Indo-Pacific region and Indian Ocean is the closely related species Abudefduf vaigiensis.
Maintenance: This fish will readily eat all kinds of live, frozen, and flake foods and algae. Finely chopped meaty foods (like brine shrimp) can be fed regularly. It is best to feed small amounts several times a day. In a reef situation they don't really need to be fed very often at all.
Social Behaviors: Like all damselfish, they can be territorial and aggressive, especially as they get older. Should not be kept with others of the same species. Can be kept with other larger fish but watch them closely to be sure their aggression doesn't become destructive. Inhabits inshore and offshore coral reefs, usually found at depths between 1 and 12 meters.
Breeding/Reproduction: Some of the damselfish have been bred in captivity. See general breeding techniques under Clownfish on the marine breeding page.
