Care

Astrapogon stellatus is a relatively hardy species that can be a good choice for both novice and experienced aquarists. They prefer a well-structured aquarium with plenty of hiding places and a peaceful environment. These fish are not aggressive and do well in groups, making them suitable for a community tank with other non-aggressive species. They thrive on a varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Conspicuous Cardinalfish are mouthbrooders, with males carrying the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, providing an educational experience for the aquarist. Breeding them in captivity can be challenging but rewarding.

Habitat

The natural habitat of Astrapogon stellatus includes shallow reefs and seagrass beds in the Western Atlantic, from Florida and the Bahamas to Brazil. They are typically found in areas with calm waters and are known to associate with the long-spined sea urchin Diadema antillarum for protection during the day.
