i think they are acans

That's what I thought, but their shape is just slightly different. Each polyp kind of curls around the surrounding polyps a little bit differently than other acans do.

Looks like acans that aren't fully inflated just yet. They'll probably get more rounded as they inflate.

acan that is hungry maybe... taking in water for feeding in the water column.
