Would removing the mud/clay the moss is growing into be needed for it to grow in an aquarium? Or is it better to to leave the mud/clay and plant it in. I’ll be attaching it onto wood and not substrate. It is a mini fissiden moss.

I tried washing the mud off but it is like solid and if I do manage to break it off so does the moss. Which becomes smaller pieces and just does not seem possible. It is a mini fissiden moss. What should I do?
