Re: 6 gal heaven Are you running CO2 or just using the organics in the substrate, and what is your lighting (type and wattage) intensity? If it's a low-light setup with natural CO2 production I suggest letting the fern be your main plant with something like Fissidens moss or maybe some Anubias 'nana-petite' to go with it.
On that note, I noticed a neat thread on lighting cycles in the DFW club sub-forum that you may be interested in reading.
