Blackspot Tang/Surgeonfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Mozambique and Maldives to the Western Pacific.

Size: 20 inches (50 cm)

Natural Environment: Inhabits deep reef slopes and usually found at depths below 100 feet (30 m) where it feeds mainly upon microalgae and diatom film on rocks.

General Husbandry: Rare in the trade having a laterally compressed body and small mouth, such as angelfishes and butterflyfishes, with a grey-brown body and some orange/red on the dorsal and anal fins, and a small black spot on the upper gill plate.

Can be maintained in reef or fish-only aquariums having wide-open swimming areas and somewhat turbulent, well-oxygenated water flow.

Requires a varied vegetable diet, including fresh macroalgae, Spirulina, zucchini, broccoli, dried seaweed (Nori), and enriched vegetable flakes, and requires two or three feedings per day. Will browse on filamentous and microalgae.
