I have a round moss plant and when I bought it I was told it would divide into two. I noticed that it is no longer a round ball but it is kinda caved in on top. I called the pet smart where I bought it and at first they told me they don't divide and then I was told if I wanted it to divide I would have to do it by hand. Then they told me yes it would divide on its own. I would like to know if anyone knows anything about this plant. Do they divide on their own and if so how long does it take and how can u tell when they are dividing. Also do goldfish eat the plant? Thank u so much.
