I kinda fragged the zoanthid, just a small piece and bingo found the pest. I took a bowl with some tank water outside in the sun and removed all traces of the little bugger(and some bubble algea) then discarded the water of course. Then I rinsed it with some tank water, then through out that water. How will I remove the tiny ones? The only aiptasia left is on a rock with some shroms and xenia, they are tiny, like baby feather dusters.
