video: coordinated nest defense in the convict cichlid

Cordinated nest defense against fry predators by a pair of Convict cichlid (Amatitlania siquia), a monogamous tropical fish species. The video was recorded in Lake Xiloà, Nicaragua. In natural environment, the eggs and young are highly vulnerable to predation from other fish species or even convict cichlids (cannibalism). Both parents perform intensive coordinated defense of the nest entrance in order to repel intruders sometimes much larger than themselves.
