Cryptocoryne yujii

About this plant

Cryptocoryne yujii is a described species from the Sibu area of Sarawak. The original specialist account documents bright green foliage, including leaves up to about 50 cm long, and a distinctive twisted pale spathe with a coloured collar. It is not established here as a tiny red-brown foreground crypt. Reserve room in the background rather than relying on a compact supplier size claim. Do not transfer ordinary wendtii water-hardness advice to this Bornean species without evidence. Its precise numerical aquarium care limits remain undocumented in the sources used for this profile; stable, carefully observed cultivation is more appropriate than a fabricated tolerance chart. Keep the rooted crown at substrate level and allow space for long leaves. Specialist material documents cultivation, but numerical water-hardness, temperature and CO2 limits are not established here. Do not infer them from the care of an unrelated compact crypt. Maintain stable conditions, observe new leaves and avoid repeated relocation. Rooted daughter plants may be divided when well established. Care ranges, where supplied, describe reported cultivation conditions rather than measured lethal limits. Width and nutrient concentrations are left unspecified where no defensible form-specific values are available.
