Mushroom corals are some of the toughest soft corals in the hobby, and a great choice for starter corals. They also add a spot of color to low light areas in mature reefs.
This is an especially colorful strain of Ricordia covered with fluorescent orange bumps, with a bright fluorescent green mouth. It is the brightest Ricordia in my collection by far.
The image shows an example of the mushrooms for sale, and the one you receive will come from the same strain. These are pretty large mushrooms, about 1-2 inches fully expanded. Because of natural variation among specimens, the mushroom you receive may look slightly different from this image.
