Description
Blue Back Dwarf Angelfish – Centropyge colini
Overview:
The Blue Back Dwarf Angelfish is a stunning marine fish with a bright yellow body contrasted by a deep blue dorsal region, creating a striking two-tone appearance. Its small size, bold colors, and active swimming make it a standout in both reef and fish-only aquariums.
Origin:
Native to the Western Pacific, particularly around Melanesian and Micronesian reefs, where it inhabits coral-rich lagoons and reef slopes.
Feeding:
Omnivorous – thrives on marine algae, spirulina, mysis shrimp, brine shrimp, and high-quality angelfish pellets or frozen foods. Supplement with seaweed sheets to maintain vibrant coloration and health.
Tank Mates:
Compatible with peaceful to semi-aggressive fish. Territorial toward other dwarf angelfish, so keep singly or in a large tank. In reef aquariums, may occasionally nip at LPS corals, soft corals, or clam mantles.
Aggression:
Semi-aggressive – active and territorial, particularly with other dwarf angelfish.
Experience Level:
Intermediate – hardy once established, but requires a stable aquarium with plenty of live rock for grazing and shelter.
