$ 13.95 $ 15.95
Dark Spleenwort Water Fern is rare because it is very slow growing. It only requires low to moderate lighting and nutrient rich soil, although its growth rate can be increased through CO2 injection/supplementation. It reproduces through rhizome division and the production of offshoots, and it thrives in areas with strong water currents. Dark Spleenwort Water Fern should not be planted with its rhizome (roots) fully buried in the substrate because it will rot and recede. Instead, it can be attached to rocks, driftwood, and other decorations in the aquarium, or it can be planted on top of the substrate as long as the roots are not completely buried. Due to its delicate leaves, it should never be housed with large crayfish, medium to large cichlids, goldfish, or any other animals that are prone to picking at plants.
CO2 supplementation is beneficial, but not necessary for this plant. Like most plants, Dark Spleenwort Water Fern will benefit from supplementation such as Seachem Flourish, Flourish Excel, Nitrogen and other plant supplements.
