1. Nice tank.
2. Could be a change in lighting - or a change in zooxanthellae due to your lighting>?

Micromusa/acans are almost guaranteed to change color from one type of light to another and change from the intensity of the light as well.

I usually try to buy from vendors that are growing them under the same type of lights I use so the change is minimal.

I'm with Kristopher, its most likely lighting. Bought 4 from two dif high-end online sellers a couple months ago and they all have changed colors since then under cheap LEDs.
