Anthelia, which seemed to be a good idea at the time, is now growing all over my clams. About a week ago in desperation I tried to scrape it off, and then wound up scissoring it off. The stuff comes back like Terminator II however, and I was wondering if anyone could suggest a more permanent solution? I dislodged one of the clams messing with it, and it took several days to look good again, so I would really like to minimize how much screwing around I do. They are both T. crocea BTW and are otherwise healthy, though they seem to have appreciated my removal of the anthelia.
