Longspine Cardinalfish: Shimmering Beauty for Your Reef

Add a touch of tranquil elegance to your marine aquarium with the ethereal Longspine Cardinalfish. These peaceful, schooling beauties bring gentle movement and subtle colouration to any well-established reef or community tank.

Overview

The Longspine Cardinalfish (*Zoramia leptacantha*) is a captivating marine species, showcasing a semi-transparent, silvery body adorned with iridescent blue and yellow accents around its eyes, head, and fins. Known for their distinctive tall first dorsal fin, these cardinalfish are typically seen forming graceful, dense schools, creating a mesmerizing display within your aquarium. They are primarily nocturnal, often seeking shelter among corals and rockwork during the day, becoming more active as dusk settles.

Care Level

Considered easy to moderate in care, the Longspine Cardinalfish is a peaceful and docile species, ideal for community tanks. They thrive best when kept in groups of 5 or more, which enhances their natural schooling behaviour and reduces shyness. They are compatible with most other peaceful marine inhabitants, but care should be taken with very small shrimp, which they might occasionally prey upon.

Tank Essentials

A minimum aquarium size of 100 litres is recommended to house a small school comfortably. Replicate their natural reef habitat with ample live rock, branching corals, and shady hiding spots. Maintain stable water parameters: pH between 8.1-8.4, a temperature range of 23-27°C, and a specific gravity of 1.020-1.025. Subdued lighting is appreciated, especially during their active nocturnal hours.

Diet

Longspine Cardinalfish are carnivores, primarily feeding on small crustaceans and zooplankton in their natural environment. In the aquarium, offer a varied diet of high-quality meaty foods, including enriched frozen mysis shrimp, brine shrimp, finely chopped marine preparations, and quality marine flakes or micro pellets. Feed multiple times daily to ensure all individuals get sufficient nutrition.
