The threadfin cardinal, scientific name Zoramia Leptacantha, is a peaceful fish. Their minimum tank size is 20 gallons. Their maximum size is 2 ½” and they can live up to 5 years. The threadfin cardinal is a carnivore and should be fed small pieces of frozen food such as mysis or brine shrimp. Cardinals are schooling fish. It is possible to keep them alone, in pairs, or in groups. As long as there is adequate space keeping an odd or even number will not matter for these fish. Threadfin cardinals are reef safe and will not bother coral or invertebrates. Threadfin cardinals may prey upon small shrimp they can fit in their mouth. Threadfin cardinals will often be seen sitting still in the water during the day. During the night the threadfin cardinal will find crevices in rocks to hide in.
