The species looks very similar to the related Indian sailfin tang (Zebrasoma desjardinii), which has replaced Z. velifer in the Indian Ocean. The key to keeping them apart are the spots on the tail of Z. desjardinii. Zebrasoma velifer has been renamed in 2012 from Z. veliferum to Z. velifer, which you will often see in books.
