Not gonna take a photo cause I doubt it'd show up. Anywho, on two of my supposedly "dead" rocks (have other live rocks in the tank) there appears to be feathery snot growing. Almost looks like clear mold. I'm concerned as to weather this is nice flora, or something I need to try and get rid of. Anyone have ideas? I'm new to this, and my experienced friend who is help me didn't have any ideas.
