How mobile are mushrooms?

[SaltyDr]

I have what appears to be a brown discosoma mushroom that arrived as a hitchhiker on my liverock. This thing moves all over the place, and quite quickly (well, more like an inch in a minute or so) What seems odd is that it likes to hide and never comes out when the lights are on. Does this seem normal? I'll get a pic when I can, but this little guy can be elusive.

inch per minute? that's no coral my friend. maybe a mushroom attached the the shell of a snail? got a pic?

I'll try to get a pic. I know, this thing moves a lot faster than I would hve thought. I never actually timed it, but it can cross a rock in 10 minutes or so. Weird.

Mushrooms move around mostly by detaching their base and floating in the current. Other than that, they only "move" about one body length over the course of a week or so. Anything moving faster than that is probably not a mushroom.

We had a shell with a red discosoma attached to it, and one of the hermit crabs changed his shell for the one with the mushroom on it. He had his very own battle helmet. :)

I agree with the above, I am skeptical about a mushroom moving at that rate =) Probably attached to a hermit crab shell

Now, I've had a mushrooms move it's body length in a 24 hour period, but not an inch a minute. I would definitely suspect other modes of transportation than an actual physical form of locomotion coming from the mushroom

I have answered the mystery! What I thought was a mushoorm is really a fleshy limpet! It was always seen at night and usually on the underside of a rock so I never got a good look at it. I haven't read anything favorable about them, so I think it's gotta go...
