You Probably Didn't Know... Angelfish Fact

Did you know...

Aggression by angelfish to an opposite sexed intruder was markedly reduced when the mate was not there. Defence of their territory was not as vigorous just after the eggs had been released and fertilized. The angelfish of both sexes attacked intruders of the same sex more intensely than they attacked the opposite sex. Male angelfish were more aggressive than their female counterparts. It goes to show that their aggression to intruders serve to maintain their special bond!
