Thank you for the link geronimo, and thanks for the feeding to PP.

I fed it krill morsels today, and one of the ?mouths? had a piece that wasn't as fine fall in the middle of him, he munched slowly (like 10 min), and brought it within himself. Most particles pieces were very fine, and the other ?mouths?didn't display any obvious eating like the one, is this sufficient? Are they still eating?
