Additional names

Bangai Cardinal, Banggai Cardinalfish, Bangaii Cardinal, Longfin Cardinalfish, Kaudern's Cardinalfish


Endangered in the wild apparently restricted to Banggai Islands, Indonesia in the Western Central Pacific Ocean.[1]


Males have a more angular head with an extended second dorsal fin, whereas the female has a more rounded head with a shorter dorsal fin, they can however look very similar to the untrained eye.


They will breed readily in captivity, they are mouthbrooders, the male holds the eggs. After 18-21 days the eggs hatch, the male releases fully developed fish on day 21 to 24.

Tank compatibility

A good beginner reef fish, hardy but can be territorial to other Bangai's or fish similar in shape to them. Best to keep a pair, or a larger group.


Will take most foods including bloodworms, feeder shrimp and marine flesh.

Feeding regime

Twice a day.

Environment Specifics

An Indonesian fish which is threatened due to over collection. Also appreciates spacious tank with places to hide and swim.


Not a very active fish, will often hang in one place, move, and hang about some more.


Very distinctive fish. Iridescent white-silver base colour with three vertical black stripes down the flanks extending into the fins. Elongated tail, with white spots on all fins and flanks.

Special Note[edit]

This fish has now been listed as threatened/endangered in the wild. Please ensure, if you are considering buying this fish, that the specimen has been captive bred and not wild caught. This species is well-known as a profuse spawner in captivity, with the male mouthbrooding the eggs. If the female is overly amorous the male will starve because he will not eat when mouthbrooding; if such a situation arises, separate the male until he is revitalised, and ready to handle another mouthbrooding.
