Mystery ID Please

I found these in my tank today. Have no clue what they are they look like a cross beetween a polyp and a micro duster. They are about the size of a small zoanthid. Any ideas will be welcome.

They are actually a type of small anenome. I have them in a few of my tanks, but can't remember their name. They stay small, about the size of a dime or so, and are actually sought after by some folks.

They are not a nuisance like majoanos or aptasia.

corynactis?

do a search for "white ball anemone", pink ball or similar descriptions.

pseudocorynactis. Here's a link, you'll find them a little ways down the page. http://www.advancedaquarist.com/issues/oct2002/invert.htm
