Common name: Blue-spotted spinefoot

General information

The Coral Rabbitfish, also known as the Blue-spotted Spinefoot, is a species that adds both beauty and utility to the reef aquarium. Its scientific name is Siganus corallinus. This fish is known for its striking blue spots and lines against a yellow to olive background, which can vary in intensity depending on the individual and its environment.

Rabbitfish are generally peaceful but can be territorial with their own kind. They are equipped with venomous spines on their dorsal and anal fins, which they use for defense. It's important for hobbyists to handle them with care to avoid painful stings.

Care

Coral Rabbitfish require a spacious tank with plenty of swimming room and hiding places. They are herbivores, so a diet rich in marine algae and vegetable matter is essential for their health. They can also help control algae growth in the aquarium.

These fish are hardy and adapt well to life in captivity if provided with the right conditions. They should be kept in a tank with stable water quality and a well-functioning filtration system.

Reproduction

In the wild, Siganus corallinus forms pairs during the breeding season. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic before settling down and growing into juveniles.

Breeding them in captivity is challenging due to their spawning behavior and the difficulty in raising the planktonic larvae.

Habitat

Coral Rabbitfish are found in the Indo-Pacific region, from the eastern coast of Africa to the islands of the central Pacific. They inhabit coral reefs and lagoons, often found in shallow waters where they graze on algae.

Their presence in the aquarium helps mimic their natural role in the reef ecosystem, contributing to the balance and diversity of the tank's community.
