One of the species of those Cats sneaks eggs into the spawning site of mouthbrooding cichlids. The eggs are picked up and hatch before the cichlid eggs and their first food is the cichlid eggs. So the cichlid ends up releasing nothing but catfish, which eat any cichlid they can catch (usually at night when the cichlids are asleep) and fit in their mouth.
