Mushroom corals are some of the most versatile corals available to keep. Mushroom corals can maintain good health in less than ideal water parameters, making them a top pick for aquarium beginners. Mushroom corals are not too picky either; they can be placed most anywhere in your tank with low to medium lighting and water movement. Mushroom corals will enlarge when they are happy with their placement, making it clear whether they are happy where they are or not.
