Saltwater dwarf angelfish, belonging primarily to the genus Centropyge, are among the most popular marine aquarium fish due to their brilliant coloration and compact size. Most species typically reach only 3 to 5 inches in length. Dwarf angels possess the deep-bodied, oval silhouette of their larger counterparts but are far better suited for home aquariums. They are found throughout the tropical reefs of the Atlantic, Indian, and Pacific Oceans, where they spend the majority of their day darting in and out of rocky crevices. Their social structure is fascinating, as they are protogynous sequential hermaphrodites; they live in small harems where the most dominant individual transitions from female to male to lead the group.
In a captive environment, these fish are prized for their active personalities and “grazing” behavior. They are omnivores that constantly pick at live rock to find algae, detritus, and tiny invertebrates. This helps keep a tank clean, but also leads to their reputation for being “reef safe with caution.” While many coexist peacefully with corals, some individuals develop a habit of nipping at the fleshy polyps of stony corals or the mantles of clams. Dwarf angelfish are also notably territorial, often showing aggression toward other angelfish or newcomers that compete for their foraging space. Because of this, they require an aquarium with plenty of hiding spots and established rockwork to feel secure and establish their boundaries.
