🐠 Bluefin Angelfish (Centropyge multispinis)
Marine Reef-Safe-With-Caution Dwarf Angelfish • Dusky Blue-Black Display Fish • Bold Active Personality • Intermediate Marine Fish
 
📋 The Bluefin Angelfish (Centropyge multispinis), also known as the Dusky Angelfish or Many-Spined Angelfish, is a striking dwarf angelfish with a dusky dark-blue to near-black body, subtle darker vertical lines, and vivid electric-blue edging along the dorsal and anal fins.
Native to the northern and western Indian Ocean, from East Africa and the Red Sea across to Sri Lanka, Sumatra, and Thailand, this species is found alone, in pairs, or in small harems among rocky rubble and reef slopes.
Bluefin Angelfish are generally considered reef safe with caution — many specimens leave corals alone, but individuals can nip at stony and soft corals, clam mantles, feather dusters, and anemones, particularly if underfed. A well-fed fish with plenty of algae to graze significantly reduces this risk. This is also a genuinely bold, active, and somewhat territorial species — keep only one per tank unless the aquarium is very large (5 feet or longer), and it's best added as the last fish to an already-established system.
With a spacious tank, ample algae, and a varied diet, it thrives as a Bold Dusky-Blue Reef Display Fish.
