Care
Blackfin Cardinalfish are relatively easy to care for, making them a good choice for both beginner and advanced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting and a quiet environment. A varied diet of small meaty foods, such as mysis shrimp and brine shrimp, will help maintain their health and coloration.
Reproduction
In the home aquarium, Blackfin Cardinalfish can exhibit interesting reproductive behaviors. They are mouthbrooders, with the male carrying the eggs in his mouth until they hatch. This parental care increases the chances of survival for the offspring, making them a fascinating species to observe during breeding.
Habitat
Apogon atradorsatus is found in the Western Pacific, from the Philippines to northern Australia. They typically inhabit coral reefs and lagoons, often seeking refuge among the branches of corals or in crevices during the day. In the wild, they can be found at depths ranging from shallow waters to about 30 meters.
