Care
The Japanese Pygmy Angelfish is known from southern and central Japan and the north-western Hawaiian Islands, where they are found over rocky and coral reefs, at depths between 12-60m (39-197ft). This beautiful angelfish is rarely seen in the trade, and as such, tends to command a hefty price tag when it is available. Although it does not grow to a huge size, this is one of the larger
Centropyge species and is an active fish that does require a good amount of space. The bigger the tank, the better, as then the fish is much less likely to continually pick at any one particular sessile invertebrate and cause irreparable damage. Also, ensuring that the fish is well-fed means that it should not pose any real threat to reef aquaria - although occasional specimens may nip at some invertebrate life (see below) it should be noted that this only usually occurs if dietary requirements and feeding frequency are not being met. Careful observation is recommended. The Japanese Pygmy Angelfish should be kept singly and not with any other members of the
Centropyge genus. Although this is a fish that can be quite shy when first introduced to the aquarium, and may take a little time to settle, once it has become accustomed to its surroundings, it can be rather territorial when new species (particularly docile/peaceful fish) are introduced to the tank afterwards. For this reason, we recommend that the Japanese Pygmy Angelfish is the last addition to the aquarium. Good water movement is much appreciated, and plenty of live rock is essential for shelter/grazing. Acclimatise carefully and ensure that the tank is well mature before adding a Japanese Pygmy Angelfish. Keep water quality high at all times. The fish pictured here is a juvenile specimen; as the fish matures, the pattern and colours will change with the anterior half taking on a much more orange hue with the spots on the flanks becoming finer and more numerous. The ocellus on the posterior of the dorsal fin will also disappear. A stunning fish in both juvenile and adult colouration. May also be seen on sale as the Interruptus Angelfish.
Feeding
Should be offered a varied diet including Spirulina & marine algae as well as meaty fare such as vitamin/Spirulina-enriched brineshrimp, Mysis shrimp, special sponge-based Angelfish preparations, and finely chopped krill/squid/cockle/mussel. Feed small amounts 3 times per day.
Breeding
The Japanese Pygmy Angelfish has not been bred in the home aquarium, although it is being bred commercially on a small scale. In the wild, these fish form distinct pairs and eggs are scattered in open water.
