For the latest AquaNerd Picture of the Week, we’re digging up an oldie but goodie. This image of an Acropora granulosa is one that we took a few years ago at a local fish store, T&T Fish and Reef. We originally posted the photo back in 2010, but since we were still a fledgeling little blog at the time, we felt that it didn’t get near enough love. So, we are shamelessly sharing it once again. The colony has was quite large, with the gorgeous branches and stems growing tightly together. The coral’s body sported an almost greenish hue, with the color quickly morphing into purple as you move toward each corallite. The actual polyp is sharp white, contrasting nicely with the purple background. The A. granulosa is a wonderful coral for any hard coral reef tank, and that rich purple color seems to stick around nicely despite being under really intense lighting.
