Is it okay to plant one's java fern in the gravel or should it be attached to something? I thought it could be grown either way, but just read something somewhere that said "don't plant it!"
You can also go with super glue, I've tried it and it works great.. aesthetically pleasing too because its invisible. If left in a tank with little flow, it will eventually attach to gravel..is what most sites say. But the best thing to do will be to attach it manually instead of waiting for it to attach itself, which may be never in a tank with a lot of water movement.
