Ok so I have a post similar to this but my single euyphillia I think is sick. Once someone or something touches it, it fully retracts and shows the skeleton. Go look at my other post. It has been like that but now you can see the skeleton if something touches it. My parameters are all what you expect with zeros and 2's and calcium and magnesium in check along with alk. Any ideas of what this might be? Ill post a pic soon
