I have a new colony of green star polyp and there is something coming out of it. I have no idea what it is. When I walk up to look at it closely it darts back into the coral. It looks like a bristle worm but there's more than one. So more like a tiny brittle star but it moves way to fast to be one of those. It's white Grey and black or brown... stripes on the legs.... or antenea.... I'm not sure. I know this is very vague but if I can snap a picture of it I will... I just don't know if I can sneak up on it or not....
