identification

Hi, I was rearranging my sump when I noticed one of these, then I noticed gobs of them. I found 1 in the tank a couple days ago and thought it was a premature aptasia, but there are some in the sump that have to be going on an inch long. Anyone know what these cotton ball looking things are?
