PLEASE HELP! is my BTA dyeing??

Yup, mine moved behind teh rock where it is happy now. It has gown about 30% since the picture in my profile was taken 3 days ago. They just do what they want, we have to respect that and let them live how they want. I learned that if you absolutely want them to move (for whatever reason), the easiest and safest way to do that is to move more of the waterflow in their direction. They will feel it as a current shift, and if they don't like it, they will move. Don't force a move, you can damage their foot, or worse. Be careful too, clowns may eat the anemone if they shrink too much.
