I recently got a green bay ricordea mushroom and it opened up fine and I noticed that it had what appeared to be a tentacle about 1.5 inches long that just stayed out around it. I had assumed that it was a sweeper tentacle. Now I see two thicker and shorter looking ones and one thin one, granted the others may have been there originally I cannot remember. I got a little shnibble of a red plate montipora from a friend that now has what looks like one of the larger tentacles that are on the ricordea coming out near the edge region. I'm concerned that these may actually be parasites. I really don't want the ricordea to die...
