What do you guys think about buying "sick coral"? I know of an awesome LFS that deals in all sorts of coral, and they have a hospital section that contains injured or sick coral. They write on the glass "not for sale - unless you insist". Does anyone think it is worth buying coral in this manner? Maybe to get something special at a reduced price, just to bring home and nurse back to health and eventually add to your main tank? Has anybody done this with success? Under what conditions would you avoid buying, no matter what type of coral it is?
