+1. I've got maybe 6 Walt Smith corals. While no coral stays the same colour it was when I got it in my tank, the Walt Smith ones have all morphed the most, and have taken the longest time to do it. One of my very first corals in this tank was a Walt Smith pink mini colony of some unknown acropora, it plated a bit, then went in to suspended animation from a growth perspective for over a year. In that time it turned dark green, then a really gross grey, then the grey faded to a metallic green that fluoresced under the royal blue LEDs, then the fluorescence went away and it was just grey-green, and now finally, 13 month later, it's starting to get rose pink growth tips and the body is a gunmetal green.

The rest of the Walt Smith corals have all grown incredibly slowly, and have all changed colours at least twice. Not sure if that's other people's experience, but it's made me shy away from buying them.
