Hey guys I have had a coco worm for a couple months now and he was great...was always out during day time with a huge crown. Then I noticed my powder blue tang would peck at him while he was out... Now, he only comes out at night, and his crown is much smaller...did he lose his crown and grow a new one? Any idea if these guys do this? I cant think of another reason why it would be so much smaller.... Does anyone have experience with coco worms they can share?
