Was thinking the same thing. I purchased 7 of the java fern & attached them to small rocks via the roots with super glue. All 7 are showing signs of the browning leaves. Several have the babies on their tips. I am 16 days into these plants in this newly setup tank & my anubias plants are looking rough also. At the same time my val is already sending up runners.
I will save the buce & java moss for another post.
Any hep is appreciated.
