Neon green algae, sounds perhaps could either be cyanobacteria, otherwise known as Blue Green Algae, BGA. An unsightly bactria growth, its not a true algae specifically. I won't go into details. But it should easily come off plants and rocks, a tootbrush works well for this actually. BGA usually found near the front glass on substrate.
But could also be just green spot algae, pretty normal in most tanks, easily taken off glass, again with a tootbrush or a algae/scrub pad. If left for a while, it can be stubborn to come off, a bit of elbow grease is required in that case P)
Here is a link I use sometimes when it comes to algae, can be useful as part of your research, some of that info is not entirely 100% but is a decent starting point.

Hope that helps a bit. Remember, most tanks have algae of sorts, I am exceptionally good at growing BBA .......
