The Banggai Cardinalfish is a favorite for its striking look and easy care. Their black stripes, silvery bodies, and white spots stand out in any tank. Native to Indonesia’s Banggai Archipelago, they thrive with hiding spots like live rock or corals and some open swimming space. Their low-maintenance needs suit both new and experienced aquarists. They often hover together in small groups, adding a calm presence to the aquarium.
Carnivorous, feeding on small crustaceans and zooplankton in the wild. In aquariums, provide frozen mysis shrimp, brine shrimp, or finely chopped seafood, plus quality marine pellets or flakes. Feed small amounts 1-2 times daily.
