Craterocephalus stercusmuscarum (Fly-specked Hardyhead)

Craterocephalus are small minnow-like members of the Atherinidae family of mostly marine fish. They are fully adapted to freshwater conditions however, though some will enter brackish water in parts of their range. The genus is endemic to Australia where they are sometimes known as "hardyheads".


Fish information (behaviour and breeding):

Hardyheads are schooling fish that feed on algae and aquatic insect larvae. They are generally very adaptable in terms of water chemistry and water temperature. They can be delicate in captivity though, so attention will need to be paid to diet, water quality and oxygen concentration. Some species enter brackish water but they do not need such conditions to survive. All are social, schooling species.
