Common name: Squaretail rabbitfish

General information

The Dusky Rabbitfish, scientifically known as Siganus luridus, is a species of marine fish belonging to the family Siganidae. These fish are known for their distinctive coloration and patterns, which include a combination of muted greens, yellows, and browns, often with a dusky appearance. They are equipped with venomous spines on their dorsal and anal fins, which they use as a defense mechanism against predators.

Care

Dusky Rabbitfish are herbivorous and require a diet rich in marine algae and vegetable matter. They are generally peaceful but can be territorial with members of their own species. Suitable for larger aquariums, they need ample swimming space and plenty of live rock for grazing. It's important to handle them with care due to their venomous spines.

Reproduction

In the wild, Siganus luridus exhibits a complex reproductive behavior, often forming large spawning aggregations. In the aquarium, breeding is less common, but with the right conditions, they may spawn. The larvae are pelagic and would require specialized care if one intends to raise them.

Habitat

Dusky Rabbitfish are found in the Eastern Atlantic, from the Bay of Biscay to South Africa, including the Mediterranean Sea. They inhabit various marine environments, from shallow coastal waters to deeper offshore reefs, often seen grazing on algae-covered substrates.
