When I initially received my trident fern emersed grown, all the leaves eventually browned in a week, became translucent, and a nasty fungus/algae mess. I removed all those leaves, and only some rhizomes started to shoot out new leaves. I recently received a few rhizomes that were grown submerged from another aquarist. Those leaves have started to do the same thing, turn brown, translucent, and mushy. Is this a deficiency or normal? I do have new leaves growing, but very slowly, and only one leaf per rhizome, if that. I understand these are slow growing, but I’ve never experienced Java fern melt like this before. Is trident more sensitive to parameters?
