Genus
Common name: Threadfin Cardinalfish
Scientific name: Fibramia
Fibramia is a genus of marine fish known as Threadfin Cardinalfish, which are popular in the reefkeeping hobby for their peaceful nature and striking appearance. These small, nocturnal fish are characterized by their elongated dorsal and anal fins. They often exhibit interesting behaviors such as mouthbrooding, where males carry the eggs in their mouths until they hatch. Fibramia species are generally hardy and can adapt to a variety of tank conditions, making them suitable for both novice and experienced aquarists. They thrive in groups and should be provided with plenty of hiding spaces within live rock formations.
