You need to share pictures with us, we might see things that you don't. Just keep treating it and like I said get the nem on top of an egg crate, I noticed that the foot didn't look so great earlier, but you can't just wait things out when you see them. Another member in the LPS section waited 5 days to come back and read what we said to do, he then dipped the coral with something that the LFS told him to do and it was totally wrong thing to do. The coral never should have been dipped in what it was. We're here to make sure that you're successful.
