One thing I forgot to mention in my earlier response was what I feed them. I feed them exclusively on Mysis shrimp. I feed them each a small rolled up ball of it once a week. I think the high protein has a lot to do with my luck with them.
I feel I should respond as the Rose Bubble Tip I bought from Scott is also from the same batch as the others posting here. The tank it is in is kept at 80 degrees, salinity 1.025. In the couple of months since I took the picture I posted, it has doubled in size and it's coloring has not changed at all. After reading Dr. Ron's comments about most people not feeding anemones enough, I have started feeding this one every other day - too soon to tell what effects this is having. It eats every time I feed it - has never rejected food.
