well i will try to explain what i do.... i curently have alot of flow in the tank.. well everybody knows that with alot of flow that you get spots on the bottom where the sand blows away... well my spot just happen to be right in the front, so what i did was to takne some live rock rubble in filled in the bare spot. well with all these little pieces of rock right in the front i couldnt help my self to start fragging a bunch of stuff and put it right in with the rubble. it always attaches it self in a couple days no matter what frag it is. i am guessing you can make a little frag area with some rubble and put your toadstool right in there and let it attach all by it self.
