Paedophagy

However, P. H. Greenwood, who was the first to describe paedophagia, defines it to be a feeding behaviour evolved among cichlid fishes.

In Lake Tanganyika species of the genus Haplotaxodon and Greenwoodochromis bellcrossi may also carry out this sort of feeding strategy.

[1] Other behaviours include those of the species Plecodus straeleni, which belongs to the family Cichlidae.

[1] When this species exhibits paedophagy, it has been observed circling and waiting outside the bower, which is the spawning location for many cichlid fishes.

The only exception to the fry re-entering their mother's mouth is if the mother has been disturbed by the attack and feels it is unsafe, at which point she could carry out a calling movement and all the fry would enter her mouth for a short period of time before being released.
