Batfish are large, beautiful marine fish that can easily become the focal point of your aquarium. With their bright personalities and gigantic size, they are excellent fish for intermediate tank owners. Tall and thin, they often require a large tank to swim in and are not suitable for coral reefs as they love to nibble on anything invertebrate, including coral and anemones. The most difficult aspect of keeping any Batfish is meeting their dietary requirements. A peaceful species, Batfish are quite social and prefer to school with other Batfish.
