New to the hobby? Blue Tangs are best cared for in aquariums at least 6' in length by experienced marine (saltwater) aquarists. If you're a beginner, we recommend a similar-looking fish such as the Marine (Saltwater) Yellowtail Damselfish or Freshwater Boesemani Rainbow.

Native to reefs in the Indian Ocean, the Yellow Belly Regal Blue Tang appreciates good hiding locations amongst live rock. However, this active fish also loves to swim. Therefore, ample room to roam around your aquarium is essential for optimum health. Though peaceful towards most tankmates, the Yellow Belly Regal Blue Tang will demonstrate aggressive behavior towards other fish of its own species. To keep multiple specimens, introduce the entire lot at once into a larger marine system.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine-based algae or seaweed. This diet will help strengthen the Blue and Yellow Hippo Tang's immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip and feed at least three times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.

Careful observance of the Yellow Belly Regal Blue Tang is essential as it is more susceptible to lateral line disease, fin erosion, ich and other skin parasites than many other fish.
