The whole worm is out of the tube. After I bought him, I propped him up in a hole in my live rock about 2 inches above the sand bed. Now the whole worm is on the bed while his tube is in the same location in the rock. He seems to be alive, his feathers are still open although he is now curled up. Salinity 1.023. Before this happened, he did not open out of the tube much during the previous 3-4 days. Any ideas?
