The Blue Tang (Paracanthurus Hepatus) enjoys the distinction of being one of the five most recognizable maine fishes along with the percula clownfish (Percula, Ocellaris), flame angelfish (Centropyge Loriculus), yellow tang (Zebrasoma Flavescens) and the royal gramma (Gramma Loreto). It remains the sole species under the genus Paracanthurus. Beautifully colored with an iridescent blue throughout its body with thick black markings that begin from the eyes and stretch all the way to its yellow tail.
The movie Finding Nemo featured a blue tang as one of its main characters. It is also known as the Palette Surgeonfish, Royal Blue Tang, Hippo Tang and the Regal Tang. Both the blue and yellow tangs combine to become the two most popular surgeonfishes in the hobby. The blue tang is a very affordable fish due probably because they are commonly found and heavily collected from the wild. Juveniles retail for around $25 while adults can fetch up to $80 per specimen. As with all surgeonfish, the blue tang is susceptible to ich and lateral line erosion so pick so keep a look out for any sign of the two.
Towards other species of fish the blue tang is quite peaceful. Which is why (besides its beauty) it enjoys such popularity in the marine aquarium hobby. They are hostile towards blue tangs and to a lesser extent, other surgeonfish so do not add more than one blue tang per aquarium.
In they wild they are a shoaling fish. If more than one is present in a large tank, such behavior can be witnessed. When housing more than one blue tang, they should always be introduced at the same time. Aggression is normally seen when putting a new blue tang in with an established one.
Their maximum attainable length is 12 inches. As such they should be housed only in larger tanks upwards of 100 gallons. Due to heavy collection many, specimens no bigger than an inch are common. At that size they will grow very very fast so don't be fooled into putting them in a 30 gallon tank..
Ample swimming space are needed by blue tangs so the scape should reflect this. They need at least a few caves/niches as they bed down in these areas every night.
Like most of its surgeonfish cousins, blue tangs are herbivores in the wild. They form large shoals and will graze on algae for most of the day. In captivity a vast percentage of their diet should be made up of algae based foods. Unlike marine angelfish, they are completely reef safe and do not bother corals, making them hugely popular fish for large marine reef aquariums.
Seaweed/Nori sheets are commonly offered. You can either buy seaweed produced and packaged specifically for marine fishes (Julian sprungs sea veggies) or you can go to your local supermarket and buy some nori sheets there. Always buy plain, unflavoured nori. They sometimes come with spices so you want to avoid those. Clip the sheet with a commercial nori clip or a device of your own doing and attach it to the side of the tank.
Blue tangs will normally consume anything offered in captivity despite the fact that they are mainly vegetarians in the wild. Meaty foods should make up a small percent of their daily diet.
Formula one and formula two food mixes are a good choice as well as krill, mysis shrimp and a high quality pellet. A highly reputable food for all marine fishes are those that are produced by New Life Spectrum.
Once in a while you'll see pet stores feeding lettuce to their tangs. Both romaine and iceberg lettuce don't offer much nutritionally so you want to avoid lettuce altogether.
