Common name: highfin coralfish

General information

The Highfin Coralfish, scientifically known as Coradion altivelis, is a distinctive species of cardinalfish that is admired for its elegant appearance in the marine aquarium. This species is characterized by its high dorsal fin and velvety brown to reddish coloration, with a lighter underside. It is a peaceful fish that can be a good addition to a community tank, provided that tankmates are not overly aggressive.

Care

Highfin Coralfish are moderately easy to care for, making them suitable for intermediate aquarists. They thrive in a well-established aquarium with plenty of hiding places and a stable environment. These fish are nocturnal and prefer dimly lit conditions during the day. They accept a variety of foods, including small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Coradion altivelis are known to form monogamous pairs during the breeding season. They are mouthbrooders, with the male taking responsibility for carrying the eggs in his mouth until they hatch. Breeding them in captivity can be challenging due to their specific mating rituals and the need for pristine water conditions.

Habitat

The Highfin Coralfish is found in the Western Pacific, from Indonesia to the Great Barrier Reef and north to Japan. They are typically associated with coral reefs and prefer areas with rich coral growth and moderate currents. In the wild, they can be found at depths ranging from shallow waters to about 30 meters.
