Saddleback clownfish

Description:

My personal favorite, these clownfish tend to live in larger groups then other species and I have only observed these clownfish in open sandy areas away from the reef. Also, according to wikipedia, "It is protrandous hermaphrodite, which means the male can change into a female during his life, and lives in harem in which an established dominance hierarchy manages the group and keeps individuals at a specific social rank." If you look carefully, this anemone is also covered in about 30 shrimp.

Habitat:

Coral Reef. Usually carpet anemones away from the rest of the reef.
