Except for the light color I'd say its Black Beard Algae (BBA) a member of the red algae family. Its typically caused by having at least 2 parameters out of whack. Unsteady CO2 levels - best at 30ppm, low nitrates, high iron are some factors typically that cause it. SAE and Flying Fox will eat it and your shrimp should.
Pruning, bleach dip or hydrogen peroxide to get it under control.
Seachem's Flourish Excel will also help.
