By comparison, the real moss balls will always stay round (-ish).. You can even cut them in half, and eventually both balls will form into complete circles again, albeit smaller.
I see. That is kind of what I thought but thought it was worth a try. I have so much Java Moss in my tank, I have been tossing it out all over and just thought if I could roll it up in a ball, it would take less space. ha ha
