Can you tell me if what this is?

Question

I have a Java Vern that I put in my tank and its been there for about a month or so it seems to be growing roots off of the leaves,is this new growth or is it a fungus, the roots have new leaves growing from it, should I take them off the Java Vern leaves or just leave them there.plus will this hurt the tank.

Answer 1

this is one of the ways that Java ferns reproduce: they grow new little ferns off their own leaves. Leave them on there till they get bigger then remove them and treat them the same as any other one

Answer 2

That is how the java fern reproduces. Soon a whole new plant will grow on the leaves and it will fall off and attach somewhere else.
