cichlid fish, Archocentrus nigrofasciatus , we examined whether the loss of a mate prior to spawning influences pair re-formation and reproduction. We manip- ulated an individuals’ “readiness to mate” by removing its mate within 24 h prior to spawn- ing and immediately replacing it with a similar sized
