If he is clouding you water, it is probably starting to decompose. If so, I would recommend that you remove it.
You could also bring it to the surface, remove it slightly, and if it stinks, get rid of it. If you have a temporary place to put it, it would not hurt. I had a condy anenome do the same thing, and it looks great right now.
Before destroying it, make sure it is dieing, anenomes can look rather rough for a while, and bounce right back. Sometimes mine when exceting waste look bad for a day or two. I haven't really been following your other posts to much, but atleast give it the smell test first, then if it smells ok, if you can, put it in another container to you figure out what is going on.
