Think Nemo hatched as a cute little boy fish? I mean, I did. I've watched the movie at least four dozen times; if any one would have an opinion on the film it's me. Leave it to Disney to oversimplify. This is how it really goes down:
Father and mother clownfish are tending to their clutch of eggs at their sea anemone when the mother is eaten by a barracuda. Nemo hatches as an undifferentiated hermaphrodite (as all clownfish are born) while his father transforms into a female clownfish now that his female mate is dead. Since Nemo is the only other clownfish around, he becomes male and mates with his father (who is now female). Should his father die, Nemo would change into a female clownfish and mate with another male.
I don't know about you, but that's the movie I want to see...
