I have a Coco worm that I got just over a week ago. He was fully extended in the LFS
and looked very healthy. I acclimated him and put him in my tank and he is almost never out. I have seen him stick his fan out a few times, but at the slightest hint of movement in the tank it darts back into it's tube.
Has anyone had this experience before? Is there something I can do to make it less skitish? Is it going to live much longer if it's not extending out and feeding off the water column? Please advise.
