I was out of town over the weekend. Get report from girlfriend that blood red shrimp was attacking anemone. Apparantly it was taking bites out of the base. She said it would take a bite start to walk away and turn and come right back. Her explanation was that the anemone was like crack to the shrimp. So next morning the anemone was in the powerhead. I tested for ammonia and was at zero... any other dangers? Is the anemone toxic. I did a PWC but wondering if I should continue with like daily PWC's?
