Cortez Angelfish (Pomacanthus zonipectus)
The cortez angelfish is native to tropical reefs of the eastern Pacific. Like many other angelfish species, juveniles have very different markings from their adult counterparts. The banded patterns in the juveniles may advertise them as ‘cleaner fish’, which eat parasites off the bodies of other fishes.
