As well as maybe colonizing my tank with Java ferns to help cut down on nitrates and phosphates? And will my pleco eat java ferns, don't remember where I heard this but I heard plecos stay away from Java moss/ferns. And will my oscar tear it up? if i were to add Java ferns I would add it behind my driftwood or on it to let it grow. i don't really see my oscar being picky with the decor anymore 0.o
