You do not have a strong enough light to maintain it.
Anemones need prisitne water conditions, and lots of light. That's one the reasons most end up dead within a year.
Im not picking on cmor1701d, its the standard answer or answers to the "my nem is <insert concern here>" post. I agree with the not strong enough light part, but the rest is pure conjecture.
T-5s or halide are common for keeping nems, CF
is not unheard of though. I knew a woman in our local reef club who had an amazing RBTA under CF
lighting. It did wander but the nem grew for years, it was the center piece of her tank. However, thats only one example. IME nems move for reasons we know, and reasons we don't. Based on the fact your ready to take it back, I too vote you take it back if you can do so with out injuring it and if the LFS
will take it. Perhaps even better would be to ask a fellow hobbiest local to you if they would come remove the nem. Just a thought, GL.
