hi - i am new to this forum...please forgive this dumb question: i have had a slow but steady die-out of my red leg hermits - had about 10-12 but now down to 3. all water is perfect, no new predator fish so i was stumped. but just now when feeding my (sick) BTA a piece of krill, i saw a pink and white worm coming out of the rock. it retreated right away but i saw enough to go on line and see photos and it matches this photo: http://reefcentral.com/gallery/showphoto.php?photo=178112i ... is this what is eating my hermits? thanks
