They reproduce by themselves. I don't frag the mushies, unless I have to. Usually just scrape them off the rock and leave them on the sandbed to attach itself on something.
Will let u know. At the moment, still monitoring it. Used to a rock full of it, but dwindled to almost nothing. Hope I can find a good spot for it to grow into it's former glory.
Yes the green skirt zoa on the left side of the pic. It's kinda stuck together with the sunflower.
Not sure if it's the de-nirator taking effect, or the scrubber, or increase dosage of vit c. Probably a bit of everything.
