Care

Mozambique Cardinalfish are relatively easy to care for, making them suitable for both beginner and experienced aquarists. They thrive in a well-established aquarium with stable water conditions and plenty of hiding spaces. These cardinalfish prefer a diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. It's important to maintain a peaceful tank environment as they can be stressed by aggressive tank mates.

Reproduction

In the wild, Siphamia mossambica are mouthbrooders, with males incubating the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, providing an educational experience for aquarists interested in breeding marine fish.

Habitat

Native to the Western Indian Ocean, Mozambique Cardinalfish are typically found in shallow coastal waters, often associating with reefs and seagrass beds. They can adapt to a range of lighting conditions in captivity but prefer areas where they can seek refuge if needed.
