Common name: tailring surgeon

General information

The Ringtail Surgeonfish, scientifically known as Acanthurus blochii, is a vibrant and active member of the Acanthuridae family. It is easily recognized by its striking blue and yellow coloration, with blue lines accentuating its body and a distinctive ring-like marking near the base of its tail. This species is a herbivore, primarily grazing on algae, which makes it a beneficial addition to a reef aquarium for controlling algae growth.

Care

Ringtail Surgeonfish require a spacious tank with plenty of swimming room and a well-established growth of marine algae as a food source. They are known for their active swimming habits and should be provided with a strong and turbulent water flow. It's important to maintain high water quality and stable conditions, as surgeonfish can be sensitive to fluctuations in water parameters. A varied diet that includes marine-based seaweed and algae supplements will help maintain their health and coloration.

Reproduction

In the wild, Acanthurus blochii exhibits group spawning behavior, where several individuals release their gametes into the water column simultaneously. This strategy increases the chances of fertilization. In the aquarium, breeding Ringtail Surgeonfish can be challenging due to their specific spawning requirements and the need for a large, mature tank.

Habitat

The natural habitat of the Ringtail Surgeonfish spans across the Indo-Pacific region, from East Africa to the central Pacific. They are commonly found in coral reefs and lagoons, often in clear, shallow waters where they can access their primary food source, algae. They are a schooling species and can often be seen in groups, which is a behavior that can be replicated in larger home aquariums for a more natural display.
