Centropyge ferrugata
Family: Pomacanthidae ยท Dwarf Angelfish
Also known as: Rusty Pygmy Angelfish, Rusty Dwarf Angelfish, Rusty Angel
The Rusty Angelfish is a hardy and often overlooked dwarf angelfish that deserves far more attention than it typically receives in the hobby. Its body displays a warm rusty orange-brown base color accented with dark black spots and markings, particularly concentrated on the posterior half of the body and the dorsal area. The dorsal and anal fins are edged in a subtle blue, adding a refined accent to its earthy overall appearance.
Found throughout the Western Pacific, primarily around Japan, the Philippines, Taiwan, and Indonesia, the Rusty Angelfish inhabits rocky reefs and coral slopes at moderate depths. It is relatively common in its natural range and is one of the more affordable dwarf angelfish available in the aquarium trade. Despite its modest coloration compared to flashier species like the Flame or Coral Beauty, it is highly valued by experienced aquarists for its exceptional hardiness and interesting behavior.
The Rusty Angelfish is considered one of the easiest dwarf angelfish to keep in captivity, readily accepting a wide range of prepared foods and adapting quickly to aquarium conditions. Its robust constitution makes it an excellent choice for aquarists keeping their first dwarf angelfish or those who want a reliable and long-lived Centropyge species. While it carries the standard reef-caution rating for dwarf angelfish, it is generally considered one of the less likely species to cause problems in reef aquariums.
Rusty Angelfish are omnivores that feed on algae, sponges, and small invertebrates in the wild. In captivity, they readily accept spirulina flakes, marine pellets, frozen mysis shrimp, enriched brine shrimp, and angelfish preparations. Supplement with nori seaweed and maintain established live rock for natural grazing. Feed two to three times daily.
The Rusty Angelfish is semi-aggressive and may display territorial behavior toward other dwarf angelfish. It coexists well with clownfish, tangs, wrasses, gobies, and other community reef fish. Only one Centropyge species should be kept per tank unless the system is very large.
Check CompatibilityRusty Angelfish are protogynous hermaphrodites that spawn at dusk by releasing pelagic eggs into the water column. Captive breeding remains challenging, though the species' hardiness makes it a candidate for future aquaculture efforts.
