I hope the provided picture is sufficient. Im curious if anyone is familiar with this algae, or knows what it is. It has been growing in the tank for a while, and if u cannot tell from the picture does not grow on the rock face, it spans a gap in the rock. It is very flat and seems to have structure to it. On the bottom there is a little hole almost like an entrance. Maybe its a nest? (you can see the hole sticking out right beneath the green mass)
