Dither Fish
From Wikipedia, "Dither Fish" means an arbitrary group of aquarium fish used by cichlid keeping aquarists to reduce innate timidity in some species of cichlids. This technique relies on the ability of cichlids in an aquarium to use the behaviour of other fish species as a measure of environmental security.
So this basically means cichlids such as my kribs will only feel safe when they see some fish swimming in an open area and nothing bad happened to them. No wonder before I got the dither fish, they were so shy and always hiding.
After I got some black neons and cherry barbs as the dithers, I notice my kribs are more adventurous in coming out and play.
