The anemones have almost doubled in size over the last 2 weeks because I have been feeding them more to maintain the cycle. I even added a 8th one a week ago and they all seem to be getting along fine. The one I added was scraggly when I added it, but it's already starting to perk up. I added carbon and a UV sterilizer a week ago, but the tank will be fishless for 3 months to be safe.
