Redspot Cardinalfish: A Dazzling Schooling Jewel for Your Reef

Introduce the peaceful charm of the Redspot Cardinalfish (*Ostorhinchus parvulus*) to your marine aquarium. Its shimmering body and distinctive red tail spot create a captivating display, especially when kept in a vibrant school.

Overview

The Redspot Cardinalfish is a small, semi-transparent fish adorned with subtle silver hues and a striking red spot at the base of its caudal fin. These active, yet graceful swimmers are best known for their shoaling behavior, moving together in a mesmerizing display. While often shy when new, a settled group will become a prominent and engaging feature in your mature reef aquarium, particularly during their more active evening hours.

Care Level

Considered moderate care, the Redspot Cardinalfish thrives in peaceful community tanks. They are best kept in groups of 5-7 individuals to reduce stress and encourage natural schooling. Ensure tankmates are non-aggressive, as this delicate species can be easily outcompeted for food or intimidated by boisterous companions.

Tank Essentials

A mature marine aquarium of at least 100 litres is recommended for a small group of Redspot Cardinalfish. Provide ample live rock with plenty of shaded hiding spots and areas of brisk water movement, mimicking their natural rocky reef habitat. Maintain stable water parameters: pH 8.1-8.4 and a temperature of 23-27°C.

Diet

As carnivores, Redspot Cardinalfish require a varied diet of meaty foods. Offer vitamin-enriched mysis shrimp, brine shrimp, finely chopped krill, and copepods. Feed small amounts two to three times daily, as they can be shy eaters.
