There's a very good chance that it is just not an aquatic plant. If you could post a pic of even do an image search and find a match that we could see... perhaps it's a java fern and the browning could be normal. I have some do that as they produce daughter plants.
In any case the ferns typically are a rhizome plant and if you bury the rhizome (roots) they can rot and the plant will die off. Usually these are attached to driftwood or rocks but large gravel substrate might not be as bad as smaller grained gravel or sand.
Please help. I bought a couple El Niņo ferns from the Pestmart without knowing anything about them.
Can anyone tell me anything about them? They're getting black around the edges of the leaves and I fear they will have to go if I can't get them healthy.
Thank you so much! Links appreciated, I can read!
El Niņo ferns are Bolbitis heteroclita. Some people do use it in aquariums, but it can be a serious challenge to convert to submerged growth and keep it alive. I'd personally just consist it a terrarium plant (which is how I plan to one day keep it).
To be honest I have no clue how well the flowerpot plan will work. Aquatic ferns typically like good water circulation and having it in the pot wouldn't allow that. I really don't know how or if that changes when the leaves extend out of the water and it is half submerged. I've only started looking into growing emersed plants. Sadly about the only thing I can say is try it and let us know.

Ok. Awesome info. Redesign: I'll use a pot for the bottom. for the top I'll use one of the little dishes that you typically put underneath. A skimmer of ecolite in the top dish, set little driftwood stick on top of that, tie fern to stick. Give the leaves a little air to breathe.
Will keep you posted. Thanks again! Posted via Mobile Device
