Consorting among juvenile Midas cichlids (Cichlasoma citrinellum) in relation to own and to parents' color.
Adults of the Midas cichlid, Cichlasoma citrinellum, are either normal (N) colored or gold (G); they mate assortatively by color, and that choice is influenced by prior experience with their parents. Three groups of N and two groups of G juveniles were reared by parents which were either N or G. After some months of separation from their parents, the juveniles were tested to ascertain whether the color of their parents or of their cohorts affected their affiliative responses; they were given a choice between four G and four N juveniles. There was no demonstrable effect of either their parents' or their own color. All groups spent more time with N than with G and directed more behavior toward N. The subjects differed only in that they attacked more (at a higher rate) at N and spread their fins more (at a higher rate) at G, consistent with findings in earlier studies of the effect of gold color on dominance relationships. Thus mate choice does not result from continuous associations during development.
