To accuse of photo manipulation in an open forum is in poor taste. Even if those making such statements have personally seen the coral in question and it looked different to their eyes than the picture does, a simple "I have seen that coral in person and it was not as blue" would be more appropriate and should be enough for anyone to make an informed decision on (to buy or not).
It was already mentioned that they do keep their livestock under 20k lighting. There are other factors that could lead to a photo with a blue tint in addition to that. To flat out say the photo is doctored is wrong and IMO everyone should be given the benefit of the doubt whether they're an LFS or just some guy/gal selling corals.
Now we have people (in other states even) posting their best guess of what this coral might look like. In this case it casts a bad light on Atlantis - who does stock some of the nicest coral around, are a reputable shop to deal with, and who openly support many local reef clubs. I think they deserve a little more credit, and at least the benefit of the doubt.
I usually don't get mixed up in drama like this but I've noticed several posts like this lately and it bothers me, especially when it has to do with one of the better LFS in my area.
