The tank is nearing 7 months old. I actually went to the LFS over the weekend to buy a rock which would provide shade (my hammer was unhappy because of too much light), and they had a whole line of elegance coral, one of which bared a similar resemblance to mine (could have been mine maturing in color, or a different one...). I was tempted to get it but didn't, in fear that the hammer may have had BJD (I assumed correctly, I guess), so I didn't want to get anything new or expensive. Once I know that my other LPS are ok, then I'll look back into it.
