Because corals are marine animals, just like scallops, lobsters and swordfish. It isn't just a "preference". It is where they are designed to live. They could not survive in fresh water any more than a fresh water bass could survive in the ocean.

Not for long.Only the bull shark has evolved to live in fresh or saltwater.
In all of the world's oceans. Some can even live in estuaries (where the freshwater from rivers or streams connect with the saltwater from sea).
There are some sharks that can live in freshwater environments, but there aren't a lot that can cross over and live in both. The Bull shark is one that has been shown to have the ability to live in both saltwater and freshwater. Interestingly, they have to produce 20 times more urine when living in freshwater. (See the related link for more about Bull Sharks' freshwater tolerance.)
