Hammer - 2 heads, but one dying

[RaymondL]

This is a smaller 'younger' hammer that I acquired, which one head appears not doing well, and I don't think it's going to recover - the other head next to it I think so far looks okay. Should I cut off the one that isn't doing well, or should I just leave it? I'm not familiar what the issue(s) are if I leave the 'dying' one as is.

Personally I would leave it. It doesn't look totally gone, so there's a chance it might recover. Also, the stress of pulling it out of the tank and cutting it might have bad affect on the currently healthy polyp. Nothing happens if it dies in your tank, your filtration can handle a small dead polyp, hammers don't release toxins.
