We do feed him, like I said, 2x a week, which of course helps. Now I am afraid if we add higher lighting, it may get "burnt". I don't know. All I can say is bta's were not working for us and I told my hubby "no more"! I realized we were not doing them any good. We were supporting the trade of these little creatures and not providing them a good home. Then one day, the hubby saw the first one. It was white and I was a bit concerned. But it was labeled "white" sabae. Thought maybe that was the color it was supoosed to be. It survived and we were excited and then showed signs of turning tan. At first I thought that was wierd, but my hubby said that it was regaining it's natural color. For once, he was right.
The tanner sabae does move around the tank, but doesn't stray far from it's original spot. It opens and closes, but has never looked sickly in any way. We don't expect our anemones to last forever, but while we have it, we will continue to help it thrive.
