Oliveira et al 2009
Cichlid fish - males fight - winners experience a surge in androgen levels therefore are more likely to win a fight again. Opposite occurs when the fish loses. Experiment showed that anti-androgen in winners reversed the effects but androgen in losers does not.

Evolutionary route of coop breeding is unknown - maybe signalling to others (pay to stay or prestige) But found to be unlikely. Audience presence / social rank made no difference to feeding behaviour.
