Lipstick tang, also known as barcheek unicornfish, naso tang, orange-spine unicornfish, clown tang, striped unicornfish, black-finned unicornfish, clown surgeonfish, smooth-headed unicornfish, and probably many more monikers.

But then, genetic testing has been leading to reclassification of many species in recent times … so even Latin names can change.
