So this morning I say the crown of my feather duster detached and laying by the tube. The last several weeks he seems to have been fine. Fully opened, retracting when touched. I dose photoplakton twice a week. He did however, never really seem to have anchored down anywhere. He just laid in the sand by the rock. Is he alright? Should he be moved? I don’t see any body parts suggesting he was eaten if he escaped nor do I have anything in there that would attack him if he did. I can’t really see in the tube, but the tube looks fine. The crown is just sitting by the tube.
