Question Does Java fern grow normally in gravel?

kinda weird...

I planted a java fern in my tank gravel a few months ago, and a few weeks after planting it in the gravel, it was growing fine! (at least I think so). The problem is, all the websites and books I read about Java fern say that it MUST be tied to rock/wood or whatever. So, I bought another Java fern that was already tied to a piece of driftwood. Strangely, This one has lost almost all of its leaves, and has turned almost completely brown. Meanwhile, in the fern I just shoved deep into the gravel had new leaftips and roots coming out of the old leaf tips. Is this ok? It looks perfectly fine....

It is usually suggested that plants with a rhizome (Java Fern, Anubias) should not have the rhizome buried in the substrate. This is because the rhizome will often--but not always--rot if buried. Attaching it to wood or rock works best. The true roots, the fine hair-like threads, will work themselves into the substrate.

Java Fern will sometimes respond to a different environment by weakening, but if left alone it usually recovers. Many plants do this to varying degrees. A change in temperature, light, hardness or pH can cause these reactions. This is likely the issue with your new JF.

Thanks!

thanks... but do I need to uproot it now and plant it on a rock, or is it fine?

I've no idea if one planted in the substrate will eventually rot. It might be best to carefully expose the rhizome by pulling it up to the surface so it is not buried.
