Clown fish (Amphirion percula) is one of 27 species of anemone fish. Clownfish is a species of fish that can be associated with the anemone (Heteractis magnifica) as a refuge from predators. Clown fish can not be stung estimated because anemone fish can produce so much mucus that protects the body from the sting of anemone tentacles.

Clownfish is one of the most ornamental fish species in demand by the public because of its beautiful and sunny. However, the people do not understand to maintain reef fish in saltwater aquariums because of lack of knowledge about the physiology of a clown fish.

However, many common mistakes that make clown fish can not survive in an aquarium because it is directly transferred from their original habitat in coral reef to aquarium. Clownfish can live without united with the sea anemone if the place there are no predators that could threaten his life.
Clown fish is a fish protoandri hermaphrodites, which means the fish is experiencing a transition from male to female after reaching a certain size. However, it is not certain what size that can be classified as gender. Because this sex change in culture is still difficult to reproduce in artificial containers both controlled and naturally reproduction. Clown fishes can return to their first habitat when adult. So that it can lead to inbreeding. These fish get food to take advantage of its position in the anemone which is when many small fish and other organisms die stinging anemones.
