As juveniles, the edges on their dorsal and anal fins and the rings around their eyes are purple-blue, blue or blue-green. Juveniles may also be larger than adults and are called Atlantic yellow tang surgeonfish until they become adults. Their colors change during growth from a yellow juvenile, yellow tailed blue subadult and the blue adult phase.
