A Cichlid fish (one of which is the common Tilapia) couple will take turns to fan their eggs with their fins to increase oxygen flow.
After the young hatch, the parents continue to care for and protect them. When there is a threat from a predator, they will suck the young into their mouth until the danger is gone. Such wonderful devotion!
Many animals go to great lengths to prepare their young for survival in life. We, as parents, can make sure our young children are taken care of if we are no longer around through a trust.
