Ok, I don't mean to be rude, but you're obviously ignoring what other people have told you. I looked back through the forum history and you have been told about the problems with your husbandry... Starting a new thread won't help because we don't see what others have said.
Your Cham was recently having problems looking sick and staying at the bottom of the tank? Have you taken the advice that Camimom and others have given you? If not there's not much more we can do to help you. and I'm worried for the health of your Cham.
