Yes, and no.
Their site has both, and both are labeled as "Sarcophyton sp." You got an Sarcophtyon sp, but you didn't get a yellow morph, or a green one for that matter. Did it come from Fiji? Maybe?
The other colors are $40.5 cheaper, so I don't think you got a fair deal based upon all these pictures. Perhaps your frag browned out in shipping? Grow it out and then you will know for sure. I hope it's yellow.
