Anemonefish are fascinating parents, known for their relationship with sea anemones. In Dauin, Philippines, a pair of saddleback anemonefish used a green bottle as a nesting site for their eggs. This shows how adaptable marine life can be, as the bottle provides a safe surface for the eggs. The male anemonefish cares for the eggs by fanning them for oxygen and removing any unhealthy ones. Their ability to defend their nest from potential threats is vital for the survival of their future young.
