I have 2 acanthophyllias, one looks very happy and the other doesn’t. I moved the unhappy one because it started losing color around the mouth so I was worried it was getting too much light. It’s been a few days since I moved it but now it’s not eating and the mouth is open from time to time. Upon further examination and doing an iodine dip I saw something in its mouth (not sure what it is though) can anyone help or have suggestions?
