The floating antler fern is a short-lived perennial water fern that floats at the surface. Large plants can spread to about 1.2 m across, though aquarium plants stay much smaller. Our sources give little aquarium detail, but it is closely related to water sprite and is treated in the same way: let it float in a tank with a covered top and gentle surface movement, and remove extra plants so they do not shade everything beneath. Water figures are our estimate, not from the sources. Sources: Wikipedia (en.wikipedia.org/wiki/Ceratopterispteridoides); Wikipedia, List of freshwater aquarium plant species. Checked October 2026.
Breeding
Like other water ferns it produces small plantlets on the fronds, which grow into new floating plants.
Compatibility and tank mates
Gives shade and cover to fry, labyrinth fish and shy species. Plant-eating fish and goldfish may nibble the fronds.
