(May 7, 2015) New research on a highly social fish shows
that those reared in larger social groups from the earliest stage of life
develop increased social skills and a brain shape, or ‘neuroplasticity’, which
lingers into the later life of the fish.
A new study shows that cichlid fish reared in larger social
groups from birth display a greater and more extensive range of social
interactions, which continues into the later life of the fish. Researchers say
this indicates the fish develop more attuned social behaviour as a result of
early environments.
