Well, over the past month, the Coraline has taken off in my tank. I dont mind, its a splash of color on the back walls. Red and Pink, and a little purple. But, on some of my sand, is what looks like coraline, but its green. On the larger sand pieces, 3/16"-1/4". Under shaded areas like my anemone, theres none. Is it a Coraline, or something else?
