The Frostfin Cardinal (Ostorhinchus hoevenii) is a unique fish found among reefs and lagoons in the Indo-Pacific Ocean. They have a slightly transparent body with yellow or brown coloration, a yellow face and white tips on their dorsal fin, hence their common name "Frostfin." They reach a maximum size of 2.5" and can be kept in a tank of at least 15 gallons. They are peaceful by nature and do well in schools of 3 or more. Their diet should consist of carnivorous preparations, such as small krill, mysis or brine. They may be kept in a reef aquarium, though they should be monitored around small crustaceans. They should have plenty of live rock to hide among.
