We have shroom's about 8" under 150w mh, and they love it. Yet we also have some lower in the tank and they do just fine. As for taking them of the rock you can do it, just have to attach them to another rock(smaller) so you can move them around easier to find the sweet spot. HTH.
i agree i have some close to the light and and on the bottom,some in medium flow and some not. mine are touching and they just kinda do their thing.
