The Orbiculate Cardinal (Sphaeramia orbicularis), also known as the "Dot Dash" Cardinal, can be found among the reefs and lagoons of East Africa. Their body is a golden/beige with black spots and one solid black line, running from their dorsal to pectoral fins. They are nocturnal hunters, typically hiding among caves and rocks during the day; therefore, plenty of live rock with overhangs/caves should be accessible. They are a passive fish that does well in a peaceful fish community, and should not be housed with aggressive or predatory fishes. Make sure to have good filtration, as the Orbiculate Cardinal is very sensitive to ammonia and nitrite, and usually handles only a few tens of ppm. Their diet should consist of mysis or other frozen preparations; they may also accept pellets or flakes.
