Like most Cichlids Jewel fish are territorial & nasty fin nippers. Usually a dominant male is chasing others from his favorite spot, this behavior is common & there is never a serious damage. In case of a female's presence in the tank, the right conditions of water & temperature might trigger the male & female pairing-up, this is observed when the male & female start securing their favorite spot together. Once they have paired its highly recommended to move other fish from the tank unless the tank is big enough to hold the pair & other tank mates.
