Pterapogon kauderni
Silver body with black vertical bars and star-like white spots. Unique mouthbrooding behavior. Ideal kept as pairs.
The Banggai cardinalfish (Pterapogon kauderni) is a small cardinalfish of the family Apogonidae endemic to the highly restricted range of the Banggai Archipelago in Indonesia. Its silvery-white body dotted with fine white spots, three bold black vertical stripes, and elegantly elongated dorsal and anal fins distinguish it as one of the most ornate of all cardinalfishes. It is a mouthbrooder: the male incubates eggs and newly hatched fry in his mouth, a fascinating behavior observable in captivity. Captive breeding is relatively well established, and aquarium-raised individuals are widely available. Exceptionally peaceful and reef-safe, it makes an ideal community fish. Wild populations are classified as Endangered due to habitat loss and overcollection; sourcing captive-bred specimens is strongly encouraged.

Frozen food, pellets
Not very active — stays in one spot
Endangered — choose captive-bred specimens
They do not swim around much, so a tank of 60L or more is enough. They stay in one spot, so give them a calm place to settle.
Very peaceful and easy to keep with other fish. Best kept as a pair or in a small group.
Males brood eggs and fry in their mouth, and aquarium breeding is common. Once a pair forms, breeding is a realistic goal.
They readily eat both frozen food and pellets. Since they rarely move, feed so that food reaches the spot where they hover.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Banggai Cardinalfish is 22〜26℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Banggai Cardinalfish is 3-5 years. With proper care and nutrition, they can live a long and healthy life.
Banggai Cardinalfish typically reaches 6-8cm as an adult. Size may vary depending on care conditions and individual genetics.
Banggai Cardinalfish feeds on: Frozen food, pellets. Aim for a balanced diet with appropriate feeding frequency.
