If you just have a few corals in a bag and are carrying them on, some people were also getting a fish or two for the bag. TSA will allow you to carry on as long as they know and see there is a live animal swimming in the bag.
Just be polite and ask for a supervisor if they give you a hassle. The bag will require hand inspection. You will probably have your hands swabbed for explosive residue. The bag with fish and corals cannot go through the x-ray machine.
