Common name: Streaked spinefoot

General information

The Streaked Spinefoot (Siganus javus), also known as the Java Rabbitfish, is a species of marine fish belonging to the family Siganidae. It is easily recognized by its olive to brown body with numerous blue streaks and a distinctive dark spot on the dorsal fin. This species can grow up to 50 cm in length and is known for its peaceful temperament, making it a suitable addition to larger community aquariums.

Care

Streaked Spinefoot requires a spacious tank with plenty of swimming space and a variety of live rock formations for grazing and refuge. They are herbivorous and their diet should consist mainly of marine algae and vegetable matter. Supplementing with high-quality dried seaweed or algae-based pellets will help maintain their health and coloration. It's important to note that they have venomous spines, so caution should be exercised when handling or performing tank maintenance.

Reproduction

In the wild, Siganus javus forms large schools and spawns in open water. The eggs are pelagic, drifting with the currents until hatching. Breeding them in captivity is challenging and rarely achieved by hobbyists. However, understanding their natural breeding behavior can be beneficial for those interested in marine fish propagation.

Habitat

The Streaked Spinefoot is found in a variety of shallow coastal habitats, including coral reefs, seagrass beds, and mangrove areas. They are distributed across the Indo-Pacific region, from the Red Sea and East Africa to the Philippines, north to Japan, and south to Australia. In the aquarium, replicating a similar environment with a mix of open swimming areas and structured hiding places can help mimic their natural habitat.
