Care

Sohal Tangs require spacious tanks due to their size and active swimming behavior. They are best suited for aquariums that can provide plenty of open water for swimming as well as rockwork for grazing on algae. These fish are herbivores and thrive on a diet rich in marine algae and vegetable matter. Supplementing their diet with high-quality dried seaweed and algae-based pellets or flakes will help maintain their health and coloration.

Reproduction

In the wild, Sohal Tangs are known to form harems consisting of one male and several females. Breeding in captivity is rare, but with the right conditions, including a large enough tank and a group of mature individuals, it may be possible. The male will perform an elaborate courtship display to entice the females to spawn.

Habitat

Sohal Tangs are native to the Red Sea and the Arabian Sea, where they inhabit shallow reefs and lagoons. They are often found grazing on algae-covered surfaces and can be quite territorial, especially towards conspecifics or other surgeonfish species.

In the aquarium, providing a similar environment with strong water movement and high water quality is essential for their well-being. Due to their territorial nature, careful consideration should be given when adding other large or similarly shaped fish to the aquarium.
