Hi Frugm. If your tank is 3 months old now, you still are not ready to house an anemone. The tank needs like Yote and the others said 9 - 12 months to mature. You are going to have your water perams spot on, and you will need very strong lighting. Anemones are super delicate creatures, and there are several things that can harm them fatally in regards to keeping them in a reef tank. Please remember that in this hobby patience pays off. It's just not time for you to have an anemone yet.
