RBTA Question

[LICREEK]

I have a RBTA that in the last 6 mos. or so has split into 6 nice beautiful RBTA's. I am thinking of selling two of them, mabey bringing them to the frag prop next month. One question i have is they are all togeather on my rocks. how do you release one or two from the rock without damage. I cant direct the water flow on them as they are all to close togeather and i dont want to disturb them all...Thanks
