Aiptasia or feather duster?

[evil Nick]

Saw this under one of my rocks and first thought it was aiptasia but then closet the little feelers look more feathery than tubular.

What do you guys think. I touch tested it and it looked more like when my feather duster sucks in but I can't be sure.

Thanks
