Yup. There are a few, but it is pretty unusual.
Parrotfish can change from female to male. They live in schools that are mostly female and usually defended by a single male. If the male dies, another will female will become male to control the school. Wrass also do this.
Anemone fish (usually living in coral) will also change sex. They will live in colonies that are made up of mostly immature male fish. There will be one, large female fish that produces tons of eggs at once. Once the female dies, a male fish will take the place.
There is a species of Sea Bass that will start out female and spawn eggs. It will then change sex to male and fertilize those eggs with sperm.

There are many marine fish that do this. When there is a dominant male in the group all the other fish will remain females. But when that male is removed from the group one of the females will change into a male and become the dominant male in the group.
This is common in some types of marine gobies as well as anthius and I believe even some clowns.

It's quite common with freshwater live bearers such as Mollies and Platys. I'm not familiar with it happening in egg layers but I'm sure it does in those species as well. When there are a bunch of females and no male, one of the females will turn into a male. But, it doesn't happen the other way around. I've personally seen it happen quite a few times with my own fish over the years. I've had 3 or 4 females and no male and one of the females will turn into a male. This is a well documented phenomenon. You can find it mentioned in just about any aquarium book or aquarium website.

The only fish that I know of that can change sex are swordtails. They change from females to males. I'm sure there are other species but I'm not aware of them .

Yes some fish are asexual and can "choose" what sex they want to be, ive never heard of them changing but i would like to know what fish do this.
Since it is really hard to sex some fishes it would be cool if they just changed for them to breed, instead of getting lucky with a pair.
Like clown loaches who need 9 years to sexually mature so getting 2 and hoping in 9 years they will breed, wow lol :]

yes fish can change their sex. the most common of the fish that do this is mollies and platys from the freshwater, and from the marine (saltwater) fish the clownfish is the most famous of sex changes.
