The ocean is full of dangers, but clownfish live protected by sea anemones. Clownfish eggs are carefully nurtured by their parents and hatch. The hatched larvae drift through the harsh ocean and grow before beginning their symbiotic relationship with sea anemones.

The life of a clownfish

In this aquarium, you can see various clownfish and anemones living together. Clownfish are popular for their cute appearance, but they have an unusual life cycle. They live in symbiosis with dangerous, venomous anemones. Clownfish are able to live together because they are immune to this venom, and the anemones protect them from predators. Normally, clownfish live in groups on a single anemone, and the largest clownfish becomes the female. The second largest clownfish becomes the male, and the smaller clownfish remain immature. This is called protandry, and it is thought to be a strategy to leave many offspring by having the largest clownfish, which can lay many eggs, become the female. Clownfish are known as fish that have very strong mating bonds. In the case of the common clownfish, they lay their eggs on rocks near the anemone and protect them. The female drives away predators that might eat the eggs, and the male sends fresh seawater to the eggs and protects them from the anemone's tentacles. The pair will continue to protect the eggs together until they begin to hatch, and they will live together afterward.
