Green Hairy Mushrooms Dieing?

[Bomber]

in the last to day i havd had 2 of my larger green hairy mushrooms die! i did a water test and everything cam back 100% ok!
I just mover my mushroom rock up higher in my tank because the mushrooms weren't growing.. but is it possible that i moved them to high (they are almost under my MH bulbs) so could this be causing them to die??

Could be, what other organisms stock your tank and do you know from which part of the world your LR came from?
