| Java Fern Help
In my tank I have a large Lava rock that I built. On this rock I have two Java Ferns and starting to grow Java Moss. On the Java Fern their are hair like structures with a brown base attached to the leaves of the Java Fern, what are they, and are they good or bad. Also on the top portion of the Lava rock I think there is some hair algae starting to grow, is this bad or should it be corrected imediatley? My goal for the Lava rock is to have it covered in Java Moss with the Java Ferns to make it appear like an island.
Lava Rock 
Please see arrows to what I think is hair algae? 
The yellow arrows are hair algae I think, the red arrows point to something growing on the Java Fern
