The Vlamingi Tang, a.k.a. Bignose Unicornfish, is a large species of the Surgeonfishes that has a light blue body color that is covered in navy blue vertical lines and spots. These fish are a very docile Tang species and do well with other Tangs, as well as other fish. The Vlamingi Tang should be kept in a minimum tank size of 110 gallons. Keep only one per tank. They are voracious algae eaters.Photo by Saltwaterfish.com member, turbo21.
