You said and called yourself stupid, I jokingly agreed. I'd have felt the same way. My answer was essentially the same as "drewbaby" but directed at you and not another poster.
When I had a similar thing happen I felt the same, but covered the intake of the powerhead so it couldn't happen again and put him in a different and what I thought might be better place. He stayed. Turning off the current while an anemone looks for a suitable place isn't very helpful because he doesn't have the current to help him move and when you think he's settled and then turn the current back he may discover that the new place sucks too and back to the same vicious cycle unless the powerhead is shielded.
I only had it happen once, and made it so it couldn't happen again.
Good luck with yours and thanks for reading between the lines. You set the tone, I just followed it! Life is too short to take it too seriously!
Edit: I suppose an exclamation mark is a limited method of indicating the emotional component of a post. Guess I should have thrown a smiley face or two in there also.
