Common name: Hyaline cardinalfish

General information

The Glass Cardinalfish, Foa hyalina, is a small and delicate species known for its transparent body, which makes it a fascinating addition to peaceful reef aquariums. This species is part of the Apogonidae family, which is commonly referred to as cardinalfish. The transparency of Foa hyalina is an adaptation that helps it avoid predators in the wild by blending into its surroundings.

Care

Foa hyalina requires a well-established aquarium with plenty of hiding places and a peaceful community. They are nocturnal and prefer dim lighting or shaded areas during the day. A diet of small, meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood is ideal for their nutritional needs. It's important to maintain high water quality and stable parameters to keep these fish healthy.

Reproduction

Like many cardinalfish, Foa hyalina is a mouthbrooder. The male will carry the fertilized eggs in his mouth until they hatch, providing protection from predators and ensuring a higher survival rate for the offspring. This fascinating reproductive behavior can sometimes be observed in the home aquarium.

Habitat

Foa hyalina is found in the Western Pacific, from the Philippines to Australia. They inhabit shallow coastal reefs and lagoons, often hiding among coral branches and rubble during the day. In the aquarium, replicating this environment with live rock and coral can provide a comfortable habitat for these fish.
