Summary The attack readiness of a male cichlid, as measured by the rate of attacks directed at small blinded test fish, falls to a very low level if the animal is isolated from adult conspecifics for several weeks. It recovers again within a few days after repeated exposure to adult conspecifics. This readiness to attack could also be restored by repeated presentation of fish dummies, resembling a territorial conspecific male, over a period of 10 successive days. After being raised by this procedure, the attack readiness returned to its prestimulatory level with a half time of 7 days. Theoretical implications and the ecological significance of this long term process are discussed.
