I've been watching these in my tank for several years now and finally got a halfway decent picture of them since a colony moved closer to the front glass. Anyone know what they are called? They don't move around like a worm and the only movement they make is to shrink down when disturbed.
Sorry for the big picture, but in order to see the clear spotted tentacles, you have to look very close.
