Another predator of bristleworms
 

Besides Arrow Crabs, which I know likes to eat bristleworms, I found another animal that likes to eat them too. I saw my purple Tube anemone in my office nano swallow one up. I haven't seen too many other animals tackle them. I see bristles on the bodies and mouth of my fish all the time and I know they try to eat them unsuccessfully at times.

Nice :cool:
I have also watched my coral banded shrimp pull them out of rocks and eat them.

I've seen my red corris wrasse eat them.

My diana hogfish eats them like candy. Loves the squirmy little suckers.

Fish is still available if anyone wants to add a worm-eater to their tank...
