Apogon is a genus of marine fish known as cardinalfish, popular in the reefkeeping hobby for their peaceful nature and striking colors. These nocturnal fish are relatively small, often featuring vibrant reds, silvers, and blacks. They are known for their unique breeding behavior where males brood eggs in their mouths to protect them until hatching. Cardinalfish are generally hardy and can adapt to a variety of tank conditions, making them suitable for both beginner and advanced aquarists. They thrive in groups and require hiding places within the aquarium to feel secure.
