Common name: White Spotted Rabbitfish

General information

The White Spotted Rabbitfish, Siganus canaliculatus, is a species of fish belonging to the family Siganidae. It is known for its peaceful demeanor and striking appearance, characterized by a yellowish body with white spots and a distinctive black and white pattern on its head. This species is also recognized for its venomous spines, which it uses as a defense mechanism against predators.

In the wild, these fish are often found in pairs or small groups, grazing on algae in shallow lagoons and coral reefs. They play a significant role in controlling algae growth in their natural habitat.

Care

White Spotted Rabbitfish are suitable for both beginner and advanced aquarists due to their hardy nature. They require an aquarium with ample swimming space and plenty of live rock for grazing on microalgae. It's important to handle these fish with care due to their venomous dorsal and anal spines.

A varied diet is crucial for their health, including marine algae, seaweed sheets, and high-quality herbivore pellets or flakes. They may also accept some meaty foods, but their diet should be predominantly plant-based.

Reproduction

In the aquarium, breeding White Spotted Rabbitfish can be challenging. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic and can be difficult to raise in captivity.

Symbiosis

While not known for any specific symbiotic relationships, White Spotted Rabbitfish contribute to the health of coral reefs by controlling algae growth, which can otherwise overwhelm and damage corals.

Habitat

White Spotted Rabbitfish are found in the Indo-Pacific region, from the Red Sea and East Africa to the Philippines, north to Japan, and south to New Caledonia. They inhabit coral reefs and lagoons, typically at depths of 1 to 30 meters.
