I have a 7 month old aculeatus that is developing an odd condition toward the back of her mantle. they look like small abrasions, elliptical and roughly 2 mm. there are two of them, each about 4mm apart across the tip of the mantle. They do not change color when she does. I'm guessing that it might be a bit of overly abrasive live rock, but I didn'[t know if anyone here might have had experience with something like this? If so, PLEASE let me know what I can do to help her. Thank you Brian Los Angeles.
