Need some help regarding my BTA

[Sidsreef]

I got some rocks for my tank and had to move some sand over to get the rock on the bottom of the tank. My anemone was sitting on the side of the rock. After the sand cloudiness settled I can’t find my BTA (bubble tip anemone). I’ve been frantically looking for it and sifting through my 100g tanks sand bed thinking he got buried. I might have lost him :(…. Anyone know if a dead BTA will kill my aquarium or hurt anything?

Not in a tank that big. Your clean up clew would it eat too if you have some.
