Care, breeding and tankmates
Lighting & CO2: It requires low to moderate lighting. High light intensity causes stress to the plant and encourages algae growth on its slow-growing leaves. CO2 is not mandatory, but a small, constant supply helps maintain stable pH values, which is essential for the well-being of this sensitive species.
Nutrition & Substrate: A fertile, preferably acidic substrate (such as active soil) is crucial. It must be supplemented periodically with root tabs to ensure a constant supply of micronutrients and iron. Avoid heavy liquid fertilization in the
Water Chemistry: This species is very demanding: it requires warm water (25-30°C), extremely soft conditions (KH 0-6 dKH), and acidic water (pH 5.0-6.0). It tolerates water changes poorly if the fresh water is not pre-stabilized, which can trigger complete leaf melt.
Space Management & Placement: Given the height it can achieve, it is ideal for the midground or background of specialized aquariums or Asian biotope tanks. It should be planted in a quiet area of the tank, away from strong currents and invasive plants that could choke its root system or block light.
Pruning: Pruning is minimal, consisting of cutting away old or decaying leaves near the base of the rosette with sharp aquascaping scissors. Do not tear leaves off by hand, as this can damage the rhizome crown.
Risks & Diseases: It is highly susceptible to Cryptocoryne melt if water parameters fluctuate or if ammonium accumulates in the substrate. In case of melt, it is vital to keep the rhizome in the substrate and ensure chemical stability; if the rhizome is healthy, it will produce new leaves.
