PLANT OVERVIEW

About Tonina fluviatilis

A demanding whorled blackwater stem for expert soft-water tanks.

Tonina fluviatilis stacks whorls of fine, translucent leaves and is a benchmark 'hard' plant, thriving only in very soft, acidic, CO2-rich blackwater. Given those conditions it grows fast and beautifully; outside them it melts, making it a plant for experienced aquascapers.
