Hello!
i picked up some metallic green hammer corals from my local store. They don’t have any proper lighting for corals at all so it’s hard to see what they will look like, these were just white.
Well I drip acclimated them and put into my tank and they are still white. You can see green very faintly. This was today so they are still getting comfortable but none of my euphyllia has ever lost color. Could this be part of acclimation process?

Was the hammer extended when you purchased it? Hopefully, they come back and it gets some nice color under your lights, you might have gotten a deal on 5 heads. What are you running over your tank?
