Tag Archive: angelfish

Phylum: Chordata
Actinopterygii (ray-finned fishes)
Perciformes (Perch-likes)
Pomacanthidae (Angelfishes)

Genus/species: Holacanthus tricolor

GENERAL CHARACTERISTICS: Like their close relatives the butterflyfishes, they have a deep, laterally compressed body, a single and a unnotched dorsal fin. The most observable difference between the two families is the long spine at the corner of the preopercle common to angelfishes.

H. tricolor has a yellow anterior body with the remaining parts of body black. The caudal fin is entirely yellow.
Maximum length of approximately 12 inches (35 cm)


DISTRIBUTION/HABITAT: Western Atlantic: Georgia (USA), Bermuda, and northern Gulf of Mexico to Santa Catarina, Brazil among rock jetties, rocky reefs and rich coral areas.    Depth range 3 – 92 m (10-300 ft)

DIET IN THE WILD: Rock Beauty Angelfish feeds on tunicates, sponges, zoantharians and algae.


REPRODUCTION/DEVELOPMENT: Pair bonding suggests a monogamous relationship. Pairs usually consist of one small and one large fish as well. Pairs will spawn by slowly rising up in the water column while bringing their bellies close together, and releasing large amounts of eggs and sperm. A female can release anywhere from 25 to 75 thousand eggs each evening. This can total as many as ten million eggs for the duration of the spawning cycle. The eggs are transparent and pelagic, floating in the water column hatching in 15 to 20 hours becoming “pre-larval” angelfish attached to their large yolk sac. Has no functional fins, no eyes, or gut. After about 48 hours the yolk is absorbed developing into true larvae feeding on plankton. Growth is rapid and 3 to 4 weeks after hatching the fish will reach about 15-20 mm (0.6-0.8in) and will settle on the bottom.


REMARKS: Reports of ciguatera poisoning

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Pomacanthidae  (Angelfishes)

Genus/species: Centropyge flavissima

GENERAL CHARACTERISTICS: Yellow dwarf angelfish with blue eye ring, blue margin to the opercular cover and to dorsal, anal, and caudal fins. A preopercular spine common to angelfishes is present.

Max. size: 14 cm (5.5 in)


DISTRIBUTION/HABITAT: West-central Pacific among coral reefs in shallow lagoons.

DIET IN THE WILD The Lemonpeel Angelfish feed on algae and corals.

REPRODUCTION: As with other dwarf angels, they are sequential protogynous hermaphrodites. They start out sexually undifferentiated, develop into females, and with environmental influences, may develop into males. Males are typically larger.


LONGEVITY: Reported 11 years in captivity.

CONSERVATION:  IUCN Least concern (LC)

REMARKS: The Juvenile Acanthurus pyroferus (Mimic Surgeonfish) is a mimic surgeonfish or tang. It looks similar to the adult Centropyge flavissima (an angelfish) which is presumably an advantage as the adult angelfish has a sharp preopercular spine, while the young Mimic Surgeonfish has small, ineffective immature peduncular spines.
