The Yellow Angelfish, Centropyge heraldi, also known as the as the Yellow Pygmy Angelfish or Cherubfish, features a sold yellow body, fins, and tail. As one of the smaller dwarf angels, it thrives in a small aquarium with plenty of live rock and crevices. It is not necessarily reef safe as it can nip at corals and sessile inverts. As a semi-aggressive Angel it should not be kept with gobies, flasher wrasses, or firefish. But can be peaceful in a larger tank, or if added last. The Yellow Angelfish is easy to care for and is a hardy fish, they will graze algae, eat Spirulina, or mysis or brine shrimp. Be careful if the Yellow Angel's color begins to fade or if they get bloated as they may be sick. This is rare, though. Overall, the Yellow Angel is a wonderful addition to most tanks. They will thrive in temperatures from 72-78?? F and a pH of 8.1-8.4.
