Territorial boundaries of the male beaugregory damselfish

On six separate occasions during a two month period, there were no signific ant differences in mean attack distances by territorial male beaugregory da mselfish Stregastes leucostictus against male conspecifics. bluehead wrasse Thalassoma bifasciatus and striped parrotfish Scarus iserti. Feeding areas and patrolling areas were typically smaller than attack distances. The pre sence or absence of eggs, or the quantity of eggs within the male's territo ry also was not significantly correlated with attack distances.
