Common name: Streamlined spinefoot

General information

The Streamlined Spinefoot, scientifically known as Siganus argenteus, is a species of rabbitfish found in coral reef environments. It is recognized by its silver color with white spots and a distinctive streamlined body shape. This species is not as common in the aquarium trade as some other rabbitfish, but it can be a unique addition to a marine aquarium due to its peaceful nature and interesting behavior.

Care

Streamlined Spinefoot requires a spacious tank with plenty of swimming room and hiding places among live rock. They are herbivorous, feeding primarily on macroalgae, so a supply of marine algae or prepared herbivore diets is essential for their well-being. They are generally peaceful but can be territorial with their own kind, so it's best to keep them singly unless the tank is large enough to support a group with ample space for each individual.

Reproduction

In the wild, Siganus argenteus forms large schools during the breeding season and spawns in open water. The eggs are pelagic, drifting with the currents until hatching. In the home aquarium, breeding is rare, but providing a stress-free environment with optimal water conditions can encourage spawning behavior.

Symbiosis

While not known for any specific symbiotic relationships, rabbitfish, including the Streamlined Spinefoot, play a role in the reef ecosystem by controlling algae growth. This benefits corals by preventing algae from overgrowing and smothering them.

Habitat

The Streamlined Spinefoot is found in the Indo-Pacific region, from the Red Sea and East Africa to the Philippines, north to Japan, and south to Australia. They inhabit coral reefs and inshore waters, often found in schools, and can be seen at depths ranging from shallow lagoons to about 30 meters.
