In their natural habitat, which consists of shallow lagoons and inshore coral reefs in the Western Pacific, Mandarin fish feed all day. They do this by picking off food that is perched on the substrate or on rock surfaces.
Foods Mandarin fish eat include small snails, worms, fish eggs and copepods. Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some Copepods are planktonic and float in the water, whilst others are benthic and live on the ocean floor.
What Should I Feed Mandarin Fish In An Aquarium?
Perhaps unsurprisingly, a Mandarin fishes favorite food when in an aquarium is copepod. This is, again unsurprisingly, because they eat it naturally. It is also, however, one of the few things they will eat in captivity, and means they need a specific aquarium setup.
