Just kidding about the mutation. It has not been known
to happen. I just don't want to put an algae in my
tank intentionally. <img border="0" src="smileys/smiley11.gif" border="0">
I have a few. I got them when I had an algae outbreak & added them to the tank on the competition theory, hoping that a more complex form of algae (the balls) would out compete the other non-cummunity algae. The tank cleared overnight.
They're easy to reproduce. Wait till about 3" in diameter, & cut in half. They will curl up & for m a new ball, slowly!
