The term dither fish refers to an arbitrary group of aquarium fish used by cichlid keeping aquarists to reduce innate timidity in some species of cichlids (Barlow, 1967). The technique relies on the ability of cichlids in an aquarium to use the behaviour of other fish species as a measure of environmental security (Loiselle, 1979). Good dither fish are typically schooling species such as Danio spp., barbs and some tetra species.
