I agree that a BTA is the best one to start with. That is what I got about 9 months ago. Do your research though. Know what to look for. When mine was delivered, it was pretty bleached out. To an uneducated eye, it looked very beautiful. But I knew from my research that it needed some help. It was easy enough to get to full health with some regular feedings. My female clown took it as a host 3 months later, and the male joined her 3 months after that.
I have 4 T5's and the 2 BTAs (it split last month) sit about as low as you can get in my 90 gallon. BTA's will move to where they need to in order to get enough light and water flow. So if you don't have individual reflectors then they may just sit higher in the tank. The reflectors make a big difference in terms of lighting for anemones and coral. Do you have any?
Mine started higher in the tank, but then within a couple weeks started to get more zooxanthellae and moved down low where it has been ever since. The clone sits a few inches to its side. So the T5's must be strong enough.
BTW, I waited a year before adding my anemone. I would say 6 months is minimum. Just like corals. They require stable and clean water conditions. The BTA's seem to be a little more forgiving than others though.
