toadstools and purple mushrooms

[1234ianc]

recently bought 2 large toadstools of ellly (more than happy with them)
one of them had 3 small growths on the side that turned out to be new toadstools 2 have left the sides and are now on the same piece of rock

first question : how often will this happen
second questions : do i let them get a wee bit bigger before i move them

purple mushroom rock i also bought of elly (again more than happy with it)
its covered from top to bottom with about 30 -40 mushrooms ive placed this on top of my live rock will they move themself as there overlapping on this one piece of rock or do i need to move them
cheers all

Toadstool
You can move them but if it was me i would let them get bigger first.
Not to sure how often this will happen.

Mushroom

Yes the mushrooms will move on to the piece of rock.
