I believe SWF states min size tank at 250g

I couldn’t think of a fish to write about for this month’s column until I stumbled upon a debate in one of the XXXXX forums. The debate was over the ethics of keeping the Vlamingi tang (Naso vlamingi) in home aquariums. The Vlamingi tang grows to be a spectacular reef fish; it’s hardy, eats well in captivity, doesn’t bother sessile invertebrates, and rarely quarrels with other reef fish. Sounds like the perfect addition to your reef aquarium, right? Well, I left out one fact. It grows to an adult length of two feet! Juvenile specimens, in the two to four inch range, are frequently available for sale. If maintained well, they will rapidly outgrow the largest of home aquariums. I’m not going to tell you not to buy this fish or any other fish, but I feel it’s important for every aquarist to do their research BEFORE buying living creatures for their aquariums. All too often I see posts on the various forums that start out with “I just bought this fish/coral. Can someone help me identify it?” I don’t want to make this a column about ethics but I will present some of the arguments on both sides of the issue.
The Vlamingi tang is part of the large family of tangs and surgeonfish, Acanthuridae. It belongs to the sub-family, Nasinae, which contains the single genus, Naso. There are 20 species of Naso tangs, including the Vlamingi tang. Naso tangs are distinguished by the two fixed spines on the caudal penduncle. In other tangs and surgeonfish, the spines retract into a sheath. Some Naso tangs develop nasal protrusions as they mature. These can be small humps or single large horns, hence the name “unicornfish.”
All the Naso tangs get very large by aquarium standards. Adult sizes range from 12 inches up to 36 inches (Naso annulatus)! Most of the Naso tangs are somewhat understated in coloration, with the exceptions of perhaps N. lituratus and N. elegans. Even the Vlamingi tang is a bit of an ugly duckling. The magnificent coloration doesn’t manifest itself until the fish reaches 8-10 inches in length.
Naso tangs are primarily mid-water planktivores. They cruise reef walls in large numbers and feed on passing zooplankton in the tidal currents. They will also graze the substrate for algae, a trait that is more pronounced in some species than others (e.g., N. lituratus and N. elegans).
Naso tangs are a widespread species and occur throughout the Indo-Pacific Ocean, but are not present in the Atlantic Ocean

Keeping more than one specimen. They are a spectacular sight in groups. Joe Yaiullo maintains a group of Vlamingi tangs in the Atlantis Marine World reef aquarium. This aquarium is 30 feet in length and 20,000 gallons in volume!
Other than space, Vlamingi tangs have no special needs. They look their best in reef aquariums but don’t appreciate being crowded by corals and rocks. They literally eat just about anything, but a good diet should consist of an assortment of meaty seafood. Chopped krill, mysis shrimp, plankton, crabmeat, and clams are good sources of nutrition, along with occasional spirulina-enriched flakes and dried Macroalgae. As planktivores, they should be fed at least twice daily. Vlamingi tangs make good tank mates. They don’t exhibit the territoriality of most of the other tangs and generally ignore other reef fish.
