Recently had a tank crash, only zoas and inverts lived. Purchased some premixed water and some more live rock. Can I please get an ID of the tube-thing on my pinwheel frag as well as the two polyps in the front/middle? Also have a snail with a limpet and a similar red tube on the back. Seem to make a thread or silk-like substance. Just moved the pinwheel frag which is why its closed.
