Cichlid Fish Parenting Strategies

In Africa's Lake Tanganyika, cichlid fish face threats from predators. To protect their young, cichlids use mouth brooding, where the mother's mouth serves as a nest and nursery. However, catfish exploit this by swapping their eggs with cichlid eggs, leading the cichlid to unknowingly raise catfish young. The catfish eggs hatch first, consuming the cichlid offspring. This parasitic strategy allows catfish to dominate, highlighting a unique evolutionary battle.
