Well I have a bunch of zoa frags in my tank and they all seem to be doing good, but the one thing I noticed is they don't seem to have near the color as some of the pics I see on here. I currently just have PC's and the only food they get is what floats around when I feed my fish. what can I do to improve the color? I know my one pink zoanthid improved in color a lot after about 2 months from when I got it at the LFS.
thanks!
