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.
Swordfish primarily inhabit saltwater environments and are found in the warmer sections of the oceans, particularly in the Atlantic, Pacific, and Indian Oceans. They prefer open waters and are often found at depths ranging from the surface to about 600 meters. Unlike some fish species, swordfish do not live in freshwater.

If you dont live by the sea, you should visit any fresh food stores that you can,that is your best hope of buying swordfish.
