- Title
Opportunistic hybridization between two congeneric tropical reef fish.

- Abstract
The article discusses a study on the hybridization of two congeneric tropical fish, the wrasses Halichoeres margaritaceus and Halichoeres miniatus. It was observed in these species that the males guard several intraspecific females and mates with these females daily. The removal of male from the group allowed the largest female to undergo sex change and take over the role of the male. It was shown also that the increase in spawning frequency increases the probability of predation. One risk identified for H. margaritaceus males is that the reduction in the defense of H. margaritaceus females will probably result in adjacent males stealing spawns.
