On almost every dive out here in Thailand I manage to find some Clown Anemonefish. They were made famous by the film 'Finding Nemo' and the divers we take down love to see them.
There is a major flaw in the film's plot though, which basically centres round Nemo's dad trying to find him. In the real world of anemonefish the largest fish in the anemone is the dominant female, the rest are males of various sizes. Then what happens if the female dies or gets lost, is that the largest male turns into a female and becomes the dominant, egg laying, female. Anemonefish are what is termed sequential hermaphrodites, meaning they develop into males first, and when they mature, they become females.
It's a strange world down there.
