Looks like it’s buried in the substrate - they do better when tied/glued to rock or wood (similar to anubias).
I haven’t tried so I can’t say for sure. That said, I’m pretty sure they aren’t much of plant eaters (compared to mbunas), and Javas are usually left alone by most fish.I had the plants before i decided to convert to African cichlids, if i go peacock and haps will they tolerate the plants?
I agree.A relief it's not bba. When java ferns are happy they grow larger by increasing the rhizome and growing new leaves. If the plant doesn't like the location or is other wise not happy it does this as a last chance to continue. The "parent" leaves will start to die and the baby plants will break free and hopefully be carried else where to grow in a more favorable location. If it's only 1 leaf that's not always a indication of it being unhappy but multiple leaves usually not good. I have a terrible time with standard Java ferns, needle leaf and trident I have better luck with for some reason.
