General information

The Red Squirrelfish, Sargocentron rubrum, is a nocturnal species known for its bright red coloration and large, reflective eyes. These fish are part of the Holocentridae family, which are commonly referred to as squirrelfish due to their bushy tail-like appearance. They are relatively hardy and can be a vibrant addition to a fish-only or a larger reef aquarium with caution.

Care

Red Squirrelfish require an aquarium with plenty of hiding places and a peaceful environment, as they are shy and can be easily stressed by aggressive tank mates. They are carnivorous, feeding on a diet of meaty foods such as shrimp, squid, and various prepared frozen foods. It's important to feed them after the lights go out, as they are more active and willing to eat at night.

Reproduction

In the wild, Red Squirrelfish are known to spawn by releasing eggs and sperm into the water column, where fertilization occurs externally. In the home aquarium, breeding is rare, but providing a large, peaceful tank with multiple hiding spots can encourage natural behavior.

Habitat

Red 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. They inhabit coral reefs and rocky areas, typically at depths ranging from 1 to 35 meters.
