adding an anemone
 

hey i just added a Bubble tip anemone to my tank and it wont stay on any rock should i just let him float around

Yup. It will eventually find a spot that it likes and hopefully it won't be too close to a powerhead. Mine would settle down for a week at a time and then moved. It hasn't moved in about 6 months now so....... hopefully it will stay still now.

even if its just sitting upside down on the sand

hmmmmmm. mine never did that. I would turn it right side up.

what if you have already done that like 15 times

Maybe try and surround it with some rubble. It will hold it up right and give it a place to attch to.

alright i kinda found a divot for it and got it stuck int there with a peice of rubble

now it looks like it's turning inside out through it's mouth bad sign ?

"My anemone looks inverted – its mouth is inside out. What should I do?
This behavior is normally a sign of extreme stress and/or near death for the anemone ��
Assuming that your tank environment is perfect, the only thing you can do is wait to see
if your anemone can recover from whatever caused the stress in the first place.
Occasionally this behavior is caused when an anemone is first added to a new system and
when the anemone is not carefully and slowly acclimated. Hopefully the anemone will
recover from its shock and live on to thrive in your system."

It's dying if it doesn't recover in a few hours, you can prepare to throw it out.
