Care

Taeniamia biguttata requires an aquarium with plenty of hiding places and a peaceful environment. They thrive in groups and should ideally be kept with at least three to five individuals to promote natural schooling behavior. A varied diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is recommended to maintain their health and coloration.

Reproduction

In the wild, Two-spot Cardinalfish 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 if conditions are right. Breeding can be encouraged by maintaining a stable environment and providing a nutritious diet.

Habitat

Taeniamia biguttata is found in the Western Pacific, from Indonesia to Papua New Guinea, and north to the Philippines. They typically inhabit coral reefs and lagoons, often seeking refuge among the branches of corals or in crevices during the day.
