Chemical modulation of agonistic display in Betta splendens.

, , and . Journal of Comparative and Physiological Psychology, 90 (2): 198--202 (February 1976)

Abstract

Mirror-induced aggressive display of male Siamese fighting fish was reduced by water-borne traces of (a) a pair of male combatants, (b) a nondisplaying fish of either sex, and (c) bits of torn cadual fin. These findings may indicate a mechanism whereby males tolerate the presence of conspecifics to permit nonagressive social interactions.
