I got one of those frags from exotic at the begining of December. I took it off the plug and mounted it in some epoxy on a rock.
I have it in the middle of the tank, just above halfway up under T-5s. It looks similar to the pics posted but certainly has morphed to it's own color in my tank. I think it's getting a little too much light where I have it. The part facing the light is faded along the edges. The centers are more of a tan color. When you look straight down on it, it has a baby blue color that doesn't stand out as much from the sides.
So far since then it has started melting onto the rock on the bottom side of the frag where it's shaded (by itself) and it appears to be two small heads that have grown with good color.
Looks really good under actinics but not as impressive under full spectrum. It doesn't have the colors like you see here. I may need to move it down.
I've only fed all the heads on it one time. It's somewhat hard to feed with the short feeders it has.
