Cherub angelfish

The cherub angelfish, or pygmy angelfish, is a dwarf marine angelfish in the family Pomacanthidae, native to the western Atlantic and Caribbean. It is deep blue over most of the body with a bright orange-yellow face and blue-ringed eyes, a compact and vividly colored fish. It is a hardy but feisty dwarf angel that can be territorial, especially in smaller tanks or toward similar fish, though it is generally manageable in a peaceful community. It darts among rockwork and defends a favored cave. It suits reef and fish-only aquariums with abundant live rock for grazing and hiding, and it is one of the more reef-safe dwarf angels, though it may occasionally nip corals or clams. It grazes algae and takes a varied diet of prepared, frozen, and algae-based foods. Its small size and durability make it a good first dwarf angel.
