Mushroom Anemones in the genus Rhodactis are often kept in marine reef aquariums.
Like most mushrrom anemones, Rhodactis species are easy to keep and they do look good.
I took this picture a few weeks ago when I saw them in a local marine fish store. It has a been a while since I posted a sea creature, so here they are.
