Cryptocoryne wendtii

Overview

Cryptocoryne wendtii is one of the best-selling and most reliable aquarium plants. It comes from Sri Lanka, where it grows in shaded streams and along banks, forming compact rosettes of wavy leaves 4-8 inches tall. There are many varieties, such as 'Green', 'Brown', 'Red', 'Tropica' and 'Mi Oya', ranging from light green to reddish brown, with smooth or crinkled leaf textures.

It is popular because it grows in low light, without CO2 and in a wide range of water conditions, adding color and volume to the midground with almost no upkeep. It is perfect for beginners, community tanks and shady spots under driftwood or floating plants.

Care and tank setup

Wendtii is extremely hardy as long as it has a nutrient-rich substrate and stable conditions.

• Light: low to medium. More light brings out the color in red and brown varieties and keeps the plant compact.
• CO2: not needed; it speeds growth up a little.
• Substrate: sand, fine gravel or aqua soil. It is a heavy root feeder, so in inert substrate push root tabs next to each clump.
• Planting: bury the roots and leave the crown level with the substrate, spacing plants 2-3 inches apart.
• Placement: midground, or foreground in larger tanks; great for shaded areas.

The single most important thing to know is crypt melt: after transplanting or a sudden change in light, temperature or water chemistry, the leaves turn see-through and fall apart within days. Don't pull it out. Remove the rotting leaves, leave the roots in place, and it will sprout again in 2-4 weeks. That's why it is best not to move it and to keep water changes regular and moderate.

Fertilizing and trimming

Push root tabs next to the clumps every 2-3 months, and add a light liquid fertilizer in lightly stocked tanks. No trimming is needed; just remove old or damaged leaves at the base. Avoid moving or replanting it often, as every transplant can trigger another round of crypt melt. Over time the clumps get dense; thin them out if they crowd neighboring plants.

Propagation

It multiplies through underground runners that produce new plants around the mother, building dense clusters over the years. Once daughter plants have several leaves and their own roots, separate them carefully and replant them, expecting a bit of crypt melt. It rarely flowers in the aquarium; reproduction is vegetative.
