Tried doing some searching and what not but no definite answers. Clam has been great for us, just hit our 4yr anniversary as it was a Valentine's day gift. Anyways never had any issues at all. No need additions to the tank but for about two days now the clam has looked like this. The only thing that has been different at all is I dosed reef flux (fluconazole) Thursday night and the Skinner has been off since then. I did notice when I was cleaning the clam his foot appeared to be eating a snail shell, I didn't want to pull on the shell too hard and cause any damge. Any thoughts? Input? Any treatment to help?
