Thanks for the compliements guys. I've had these two guys for about 7-8 months now. The larger one is probably about five or six inches in diameter when fully inflated.
Condi anemones are very reef safe. Actually, I've seen other corals sting my condis, but not the other way around.
Caring for them isn't hard at all. I have only two fish in my 55 gallon, so my water is always at good levels. I have metal halide lighting so the condi's have a very nice population of zooxanthellae algae in their tissue. I spot feed them seafood from the grocery store about once every 2 to 3 days.
I'm not positive, but I think pure white anemones are light deprived. Once they are introduced into adequate lighting they tend to turn peach/beige in color (at least condi anemones do). They need to be acclimated to new lighting slowly because if they get their symbiotic algae too quickly, the anemones can die of oxygen poisoning.
All and all, they are pretty easy to care for.
