Diablito Squirrelfish

(Holocentrus adscensionis)

Squirrelfish should be added to aquariums with plenty of rockwork, cracks, crevices and caves. Squirrelfish grow quite quickly so careful consideration should be made before adding to aquariums. Squirrelfish are nocturnal and prefer dimly lit aquariums. Some Squirrelfish are capable of making loud clicking sounds. Squirrelfish have large air bladders that are affected by loud sounds such as tapping on aquarium Glass. Although quite peaceful Squirrelfish are not considered reef safe as they will consume anything small enough to fit in their mouth. Squirrelfish are better kept in small groups as pairs may pick at each other. Provide a diet rich in meaty based foods multiple times daily. When first introduced to the aquarium Squirrelfish may not readily eat. Try providing live enriched adult Brine, Glass/Grass Shrimp or Black Worms. Avoid using nets as Squirrelfish have spines on their head and gills. They also have a large preopercular spine that can inflict a painful wound.

Diablito Squirrelfish are also sometimes known simply as the Squirrelfish. They are occasionally seen in the aquarium trade. Diablito Squirrelfish have a deep, compressed body with large eyes and a long, pointed snout. They are typically silver to reddish-brown in color and have a row of large spines along their dorsal fin. Squirrelfish can grow up to 12 inches in length.

We recommend a minimum aquarium size of 75 gallons or larger for this species.
