How do i get my green stripe mushroom to spread? I have one MEDIUM sized green stripe that i bought as a frag, it kept falling off or detaching from spots that i put it in, but a few weeks back it finally stayed where i put it and its in a spot that has some decent flow so that surprised me. but anyways its been about three to four weeks and i havent seen anything as far as new growth, and it splitting at all...just wondering what i could do to help it along at all. since all i ever read is how fast they grow. it is fully attached to this rock and doing nicely, any suggestions???
