Yeah I wish I knew that before, the guys at the pet store told me it was fine and now that I'm reading about them I know I should've waited.Anemones do retract when moved, so this may be normal.
However, anemones do require excellent light and stable water conditions. The tank should also be well established. This usually takes about a year. Looking at your sandbed, your tank looks very new. In other words, your system may not be ready for an anemone. If this is the case, consider returning it to your LFS.
