Found this stuff growing under a few of my java fern leaves. I am guessing it is a type of algae. Sorry about the blurry pics :/
This picture shows what it looks like attached to the plant.
Plus, as you can see on the left-most leaf, the java fern does have a bit of black algae markings on it. Is that something I should worry about as well?
And this is what it looked like when i plucked it off, it has a reddish tint to it
