Hongslo's dwarf cichlid

Apistogramma hongsloi reaches up to 7 cm. The male is spectacular with an orange-yellow body, red dorsal and caudal fins edged in blue, and a black stripe through the eye. The female is smaller, pale yellow with a black lateral stripe. It is a territorial species but generally peaceful with similarly sized fish. The female lays eggs in a cave and becomes very aggressive to protect the spawn. It originates from acidic waters in Colombia.
