Chromis are related to damselfish and clownfish, but are typically less aggressive. They enjoy being in a school of three or more, and make a spectacular display in large numbers. Chromis are ideal fish for the reef aquarium, since they will not bother invertebrates and corals.
Most Anthias fish species are relatively hardy, but require food often in order to thrive in the home aquarium. Due to the complex social structure of Anthias, it is advisable to keep one specimen per tank.
