I have some java moss and i put it in a piece of driftwood i found. I have excess java moss and i currently have it kind of in a little ball sitting on the gravel and i was wondering if it would grow. Only part of it is on the gravel, while the rest is suspended in the water. Should i sprinkle some of my flourite on it to keep it down or anything. I was just thinking that if i did to make it flat on the substrate than it might die, since it was being somewhat covered and not have any light getting to it.
