You will receive a single green mushroom attached to a Frag plug. They will be similar in size, shape, and color to the stock pictures shown.
Mushroom Corals like to stay mostly towards the bottom to middle of the tank so that they get low to medium lighting. All powerheads and water movement sources should not be directed at them because they do not like strong water flow. Give them a small amount of indirect water movement. You can feed mushroom corals but it is not required for survival.
