We have a pinky/orange worm looking thing coming out of a spiral shell that is attached to a piece of coral. Could anyone identify what it may be be for us please?
Also the white tissuey stuff on the coral.. anyone have any ideas?
Please help if you can. We very recently, 5 days ago to be precise, set up our new marine tank. We bought what we were told was dead rock and coral. But within 24 hours our coral sprung into life and these soft tenticle looking things popped out everywhere...then a further day later it started...
