So, my RBTA is probably bleaching. It moved itself to the very bottom of the tank as soon as I put it into the tank near the top, and stretches its foot to get more light. And her color is fading, fast. Just grabbing it and moving it myself isn't really an option; her foot is behind a few very large rocks at the very bottom of my structure. I know in theory anemones move where they're good and happy. But this one doesn't seem to be doing that! How can I force it to move further up in the tank? If I cover light from it altogether - can I assume she'll start moving somewhere to get it??
