Please note, that when mushroom corals for sale are shipped, it is perfectly normal for them to be deflated and very small upon arrival. Once adjusted to your aquarium conditions, however, they will fully open.  The acclimation process for these beginner corals for sale normally takes several days.  Our Mushroom Corals for sale come in a variety of types and colors.
