• The ecology of two species of Hexagrammid fish was studied by means of underwater observation around the reefs off Benten Island in Sendai Bay throughout the year. Hitherto, it was said that Agrammus agrammus and Hexagrammos otakii coexist in the rocky reef area of the same sea region. Through the course of the present study, however, it was clarified that A. agrammus and H. otakii segregate their microhabitats from each other within a rocky reef area. A. agrammus is apt to stay on the algae growing on the rocks, and H. otakii is often observed on or under the rocks. Furthermore, some members of both species hold definite sites in their own microhabitats for several weeks. The area of the home range varies from 1-14 m^2,and the variation of area may be affected by specific characters and environmental situations. Chasing behavior for area defending was often observed in both species. The two species have similar chasing behaviors, and interspecific chasing was occasionally observed.
