Aggressive territorial defense by Pomacentrus lividus excludes P. albofasciatus from a subhabitat which the latter could apparently use. The slightly larger size, more aggressive behavior and limited home range of P. lividus compared with its competitor's smaller size, low aggressiveness and apparently wide ranging behavior seem to permit these congeneric fishes to to coexist in the coral zone at Tumon Bay, Guam.
