Anemone Upsidedown!! is that ok???

Leave it be! Anemones will always move til they are happy where they are. Also removing an anemone once it is stuck somewhere isn't very easy and could unjure the anemone, similar to Tridacnid Clams and their byssal strands and foot!

 

I agree in leaving it where it is. The area that is most detrimental to it's survival is that foot. If that gets injured, the prognosis is not good. I had some kid get a little to overzealous getting a bta out of their tank and over the next few days it turned itself upside down until the mouth disintegrated away. I got rid of it before it poisoned the tank.
