It is very difficult to get a good biotope in a just 1 foot long tank unless it is a few feet high. You will not be able to keep fish in it, only invertebrates, maybe a few shrimp or sea anemones. It is much harder to keep the water healthy in a small tank,and the appliances needed for running a salt water aquarium cost pretty much the same (if available) as appliances for a larger tank. I suggest you join a club of salt water aquarists who will be able to start you off perfectly. Your local fish/pet shop should be able to point you to a club.
