Dwarf Angelfish



Marine Dwarf Angels or Pygmy Angels belong to the Pomacanthidae family. The majority of these fish are classified in the genus Centropyge, and a few in the genus Paracentropyge. Most Angels in this group reach a size of up to four inches in an aquarium. In the wild, the largest reach an adult size of no more than six inches in length. Dwarf Angels are among the most colorful and most popular of all marine fish. All Angelfish can be distinguished from their closest relative the Butterflyfish, by their characteristic spine on the lower edge of their cheek. This spine is used defensively when the fish is harassed, but it can also be used aggressively. These Angels are found throughout the world and are most commonly associated with coral reefs. They inhabit lagoons, reef slopes, drop offs, rocky areas, rubble areas, and areas of rich coral formations. Most Dwarf Angels are found in pairs, but a few species are solitary and territorial.

Dwarf Angels usually do not mix well together in the average home aquarium unless the tank is larger than 70 gallons. If Dwarf Angels are going to be maintained together, try to vary the sizes of the fish, and add the Dwarf Angelfish to the aquarium simultaneously. This will help prevent one specimen from developing too large a territory and becoming overly aggressive.

As with most species of marine fish, sexual differences are not distinguishable. The Dwarf Angels are hermaphroditic, and the breeding of these fish in an aquarium is extremely difficult.

In the wild, the diet of these fish consists mainly of algae and tunicates. The majority of Dwarf Angels adapt well to life in an aquarium, as long as ample hiding places are provided along with algae for grazing.

They are generally compatible with: Large Angelfish, Anglers & Frogfish, Anthias, Basslets, Batfish, Blennies, Boxfish, Butterflyfish, Cardinalfish, Clownfish, Damselfish, Filefish, Goatfish, Gobies, Grunts & Sweetlips, Hawkfish, Hogfish, Parrotfish, Pseudochromis, Puffers, Squirrelfish and Tangs & Surgeons.

They are not compatible with: Seahorses & Pipefish and Sharks & Rays.
