Scientific name: Foa
Foa is a genus of small, peaceful marine fish known for their elongated bodies and distinctive color patterns, often featuring stripes or spots. They belong to the family Apogonidae, commonly referred to as cardinalfish. Foa species are nocturnal and tend to inhabit shallow reef environments where they can be found hiding among corals and rocks during the day. They are relatively easy to care for in a home aquarium, making them a popular choice for reef hobbyists. These fish are also known for their mouthbrooding behavior, where males carry the eggs in their mouths until they hatch.
