As noted before, I've had the same RBTAs for at least 6 years. They've split many, many times, and there are tons of MAASTards with my clones.

I currently have 2 in a 6 gallon nano (don't try this at home), along with some LPS and 2 clowns. They split about every 6 months or so, and do very, very well. They are under a 75w MH, but I've kept them successfully under T5s as well - and of course for the few years I had my 215 as a reef tank.

These anemones are VERY happy, and eat very infrequently. They only get what the fish get - that's all. For at least the last year, the only food they have gotten is Spectrum pellets that the clowns don't manage to steal from them. I almost never target feed them. They DO depend upon photosynthesis, and as Allan says, lighting can be critical - I believe it's been critical to my success. I've not been insanely successful in much over the many years of reefkeeping - but this particular animal has been, far and away, my most successful.
