Care

Mediterranean Cardinalfish are relatively easy to care for in a home aquarium. They prefer a well-established tank with plenty of hiding places and a peaceful environment. These fish are nocturnal and may be shy during the day, so providing dim lighting or shaded areas can help them feel secure. They thrive on a varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Mediterranean 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 if the fish are well cared for and provided with a stress-free environment. Breeding these fish in captivity can be a rewarding experience for the dedicated hobbyist.

Habitat

The natural habitat of the Mediterranean Cardinalfish includes rocky substrates and seagrass beds in coastal waters. They are typically found at depths ranging from shallow waters to about 50 meters. In the aquarium, replicating this environment with live rock and possibly some seagrass or macroalgae can provide a more natural and comfortable setting for these fish.
