Damselfish refers to members of the family Pomacentridae, except those of the two genera Amphiprion and Premnas. Other species within the family have common names that include the word 'damselfish', but in almost all cases this is qualified with an adjective or other descriptor. Many species of damselfish live in tropical coral reefs, and many of those are kept as marine aquarium pets. However, many also live in temperate climates, such as the damsels inhabiting the coast of southern California and northern pacific Mexican coast.
