The blacksmith (Chromis punctipinnis), also known as the blacksmith chromis and blacksmith damselfish, is a fish in the damselfish family. It is native to the northeastern Pacific Ocean, where it range is from Monterey Bay, California, USA, to central Baja California, Mexico.[1] This is a small fish is associated with rocky reefs and kelp forests.[1]

Description[edit]

The blacksmith can reach 25 centimetres (10 in) in length.[1] It is blue-black in color with small black spots towards the tail. The scales are large. The tail is forked. The juvenile is two-toned with a blue-grey front and a brownish-orange rear.

Ecology[edit]

Habitat[edit]

The fish lives at depths up to 46 metres (151 ft), usually close to the sea floor, over rocks, or on slopes. It also inhabits kelp forests.

Diet[edit]

The diet includes marine algae and zooplankton.

Behaviour[edit]

The blacksmith rests in rocky crevices during the night. It is known to be territorial, and, although small, it acts aggressively toward other fish.[citation needed] Juveniles are pelagic and form schools.[citation needed] The blacksmith is symbiotic with the señorita.[citation needed] When it feels that it is starting to deteriorate in hygiene it will turn until it is perpendicular to the ground, allowing the señorita to clean it.[citation needed]

Reproduction[edit]

The blacksmith spawns during summer and autumn.[citation needed] The male cleans a nesting site, then herds a female to it. After spawning, the male guards the eggs until they hatch.
