Caribbean Blue Tang Juvenile

Caribbean Blue Tang Juvenile, Acanthurus coeruleus, also go by the name Blue Tang Surgeonfish. These fish look drastically different with age. As juveniles they are yellow with blue rimmed eyes. The yellow body turns blue as the fish gets older. Adults show off deep blue stripes across their body.

These Tangs are a type of ray finned fish that belong to the Acanthuridae family. This family also includes Sawtails and Unicornfish. The defining characteristic for the Acanthuridae family, is the presence of scalpels or spines on both sides of the caudal peduncle. These are used for defense and are usually brightly coloured to act as a deterrent. For Juvenile Caribbean Blue Tangs, their weapons appear white against their beautiful yellow bodies.

Caribbean Blue Tangs also belong to the subfamily Acanthurinae. Which means these fish have one spine on each side. These spines are set into a groove and erected by curving the tail. In contrast, the other two subfamilies own fixed spines. Unicornfish, or Nasos, have one or more hooked spine, while Sawtails develop a series of spines with age. Sometimes up to seven. Sawtails are made up of the genus Prionurus only and not seen in trade.

Caribbean Blue Tang Juvenile, Acanthurus coeruleus, Ecology.

These fish live on coral and rocky reefs in the Atlantic. Their range extends from the: Gulf of Mexico, Brazil, Bermuda and to Ascension Island. The complex structures help the fish avoid predation. When threatened they will lodge themselves into a tight nook between the branches.

On the reef, Caribbean Blue Tangs mostly graze on algae. Like many Tangs, these fish can be helpful for controlling algae growth. Left unchecked, algae could outcompete slower growing coral species for space and light. Their help can be more pronounced on shallower reefs that capture more sunlight. Juvenile Caribbean Blue Tangs will also hold cleaning stations and pick algae and parasites off of sea turtles.

Blue Tang Surgeonfish In the Aquarium.

It is important to have plenty of nooks or crannies in order to imitate the natural environment. This will help your Caribbean Blue Tang establish its own territory. Aquaroche and Aquaroche shelves can be helpful for this. Hobbyists should also think about using a jump guard to stop any loses.

Caribbean Blue Tang Juvenile do best when fed a varied diet. Here they are eating a good quality pellet and flake food, such as Jbl Maris. Our Tangs are also offered ocean nutrition seaweed, that can be secured to the side of the tank with clips.

They will happily eat enriched frozen: mysis shrimp and brine shrimp and krill, in the case of the larger fish. We enrich all our frozen food with seachem garlic guard and Atvitol vitamins. These are imperative for keeping fish healthy and increasing longevity. By providing the fish with the nutrition that is otherwise lost in frozen food, these additives support the tangs immune system and helps ward off white spot.

In addition, Tangs will also eat live foods, such as copepods and amphipods, that can be cultivated in attached refugium. Our Tangs are adapted to aquarium life before being offered for sale. So they are eating dry food and/or frozen food when they leave us.

Tangs can be kept alone or in groups. If considering the latter, feel free to give us a call to discuss further. Hobbyists can keep multiple tangs together, although we encourage you seek advice if you are unsure or have questions.
