🐠 Cherub Angelfish (Centropyge argi)
Marine Reef-Safe-With-Caution Dwarf Angelfish • Sapphire Blue With Golden Face • Small Compact Size • Beginner-Friendly Marine Fish
 
📋 The Cherub Angelfish (Centropyge argi), also known as the Cherubfish or Atlantic Pygmy Angelfish, is a small but vividly coloured dwarf angelfish with a deep sapphire-blue body, a golden-orange face and chest, and delicate light-blue fin margins.
Native to the Western Atlantic, from Bermuda and Florida through the Caribbean to French Guiana, this species is one of the smallest angelfish available, making it a genuinely good option for keepers with limited space who still want to house an angelfish.
Cherub Angelfish are considered reef safe with caution — many specimens leave corals alone, but individuals can nip at LPS corals and clam mantles, particularly if underfed. It's worth knowing that this species often becomes secretive for the first several days to a couple of weeks after introduction, darting in and out of live rock — this is completely normal settling-in behaviour rather than a sign of a problem, and it typically becomes bold and constantly visible once acclimated. Like other dwarf angelfish, it's genuinely sensitive to copper-based medications, so this should be avoided or used with real caution if treatment is ever needed. Only ever keep one male per tank — territorial fights between males can be fatal.
With ample live rock, a varied diet, and patience during acclimation, it thrives as a Compact Colourful Reef Display Fish.
