What should I do if one of my coral is dying?

[Sparkpaul]

The coral is about half dead and there is some slimy stuff float and the other half is still intact but it looks like it might die.

Should I just remove it or should i just leave it in the tank?

Thanks,
Paul

What type of coral? What size is your tank?

I would just take it out for now so it doesn't mess anything else up.

I need more information to really help you out though.

I have a 100 gallon tank with a 30 gallon sump.

The coral on the top is dying.
That was the picture taken a week ago and there is less than 30 percent alive.
