Each leaf splits and forks at the tip into a ruffled, almost antler-like fringe, which gives driftwood and rock a fine, detailed texture that the plain Java Fern does not. It keeps everything that makes Java Fern a beginner favorite: low light, no CO2, slow steady growth, and leaves tough enough that most fish ignore them.
