Common name: Crown squirrelfish

General information

The Crown Squirrelfish, Sargocentron diadema, is a striking species known for its vibrant red coloration and distinctive 'crown' of spines on its head. It is a nocturnal predator, often hiding in crevices during the day and emerging at night to feed. This species is relatively hardy and can be a good choice for aquarists who wish to keep a more active and interesting fish in their tank.

Care

Crown Squirrelfish require an aquarium with plenty of hiding places and a peaceful environment. They can grow up to 9 inches in length, so a larger tank is necessary to accommodate their size. These fish are carnivorous and should be fed a diet of meaty foods such as shrimp, squid, and fish flesh. It's important to ensure that they are not housed with overly aggressive tank mates that may outcompete them for food or stress them out.

Reproduction

In the wild, Sargocentron diadema spawns in groups with external fertilization. In the aquarium setting, breeding is rare, but with the right conditions and a well-established pair, it is possible. The larvae are pelagic and would require specialized care to raise successfully in captivity.

Habitat

Crown Squirrelfish are found in the Indo-Pacific region, from the Red Sea and East Africa to the Line, Marquesan, and Tuamoto islands, north to southern Japan, and south to New Caledonia and the Austral Islands. They prefer coral reefs and rocky outcrops, typically at depths ranging from 1 to 35 meters.
