anenome on the go!!

they move it fine

Try putting it where you want it and feed it there. It might not stay in the exact spot but it might stay close when it starts to see it as an area where food is available

Anemones tend to move because they're not happy. What are your exact parameter, what size tank and what tankmates do you have?

If you can answer these questions it may help us find out why it's moving.

that is a sebae not a lta. It needs to bury it's foot into the substrate unlike the bta which likes to bury it in a rock crevice. Thi specimen is stressed as it appears to be somewhat bleached. Try placing it where you want it and place some rubble rock around the foot to keep it stablized and hopefully it will bury it's foot there....
