What ever you pay for it like others are stating is up to you.....me personally. If you like the coral. I would only buy a frag of that colony. The reason I say this, is because that coral seems like it needs to be colored up allot. It needs some proper lighting, flow and nutrients to reach its potential. If you buy the full colony, it will be harder to achieve unless you are a seasoned SPS reefer. IF you get a frag of it, it could color up to be the best coral in your collection. IMO, its impossible to tell what that coral is, or the color it will be because its too far from being healthy at this point.
