I just found these on the back glass of my 90-gallon reef tank. The colors are a dark red with light colored bumps. At first I thought it to be a mojano, then I thought it might be a ricordia. Now I'm just not sure. There are several of them growing back there with sizes ranging from 1/8" to 1/2" . Any Ideas?
