How drastic can Acros change colors?

DracoKat · Sep 30, 2016

I got some acros several weeks ago. Most of them were on the brown/tan side with whiteish polyps.
I've been keeping up with the calcium, alk and all of that fun stuff.

One of them is turning a nice shade of blue/white with green polyps. At first I thought it was bleaching out, but the blue tinge and extended polyps tell me otherwise. (and it didn't turn as fast as an acro that DID bleach out)

Is it normal for acros to change colors like this?

yes it is...all depends on what lighting they came from and what type you have.

Agreed. Lighting, alk, ph, nutrient levels in the water. All of this can cause sps (or other coral for that matter) to change colors. I've seen brown acros turn almost rainbow under the "right" conditions and I've seen some of the designer acros that go for hundreds of dollars for a quarter inch frag turn dull green/brown in another person's tank because of the parameter changes.
