Help with Mushrooms!

[bencameron27]

I think these are common mushrooms had them a couple of months, I bought them on this rock and it's starting to look a little crowded now one of the mushrooms sorta folded on itself and fell off and now I can see another one starting to do it? Will they speed onto other rock or split how do they work? Thanks

They do occasionally try to relocate, and it may be that they aren't happy with the lighting or flow that they are doing it, since they are colonial.

Okay thanks, I have moved them recently because they were on there own in the sand but I moved them closer to liverock in hope that they will spread. Thanks again.
