Sreepadma D85 Cryptocoryne Crispatula Var Tonkinensis | TC Live Plant

Cryptocoryne crispatula var. tonkinensis is a popular aquatic plant that is often sold as a tissue-cultured (TC) live plant in the aquarium trade. It is a variety of Cryptocoryne crispatula, native to Southeast Asia, particularly the Tonkin region in northern Vietnam. This plant is highly valued for its unique appearance and adaptability in aquariums.

Here’s an overview of Cryptocoryne crispatula var. tonkinensis:

Appearance:

• Leaves: This variety has narrow, elongated leaves that can range in color from light green to reddish-brown, especially when grown under proper lighting conditions. The leaves have a slightly crinkled or undulated edge, giving the plant a distinctive look.
• Size: It typically grows to a height of around 6 to 12 inches, but it can vary depending on water conditions and care.
• Shape: The leaves are lance-shaped, and the plant has a relatively compact growth form.

Care Requirements:

• Lighting: Moderate to low lighting is ideal for Cryptocoryne crispatula var. tonkinensis. It can tolerate lower light levels, but brighter lighting can encourage more vibrant colors.
• Temperature: It thrives in a water temperature range of 72°F to 82°F (22°C to 28°C).
• Water Parameters: This plant prefers slightly acidic to neutral water (pH 6.0 to 7.5), with soft to moderately hard water (3 to 10 dKH).
• Substrate: Cryptocorynes do well in nutrient-rich substrates, as they are root feeders. A fine gravel or soil-based substrate works well for these plants.

Growth and Propagation:

• Growth Rate: Cryptocoryne crispatula var. tonkinensis grows slowly but steadily when provided with the proper conditions.
• Propagation: This plant propagates via runners. It sends out small offshoots from its base, which can be separated and replanted once they have grown large enough.

Common Issues:

• Crypt Melt: Like many Cryptocoryne species, this variety can undergo "crypt melt" when introduced to new environments or if water conditions change dramatically. This is a temporary condition where the plant sheds its leaves and may appear to die. With proper care, it usually recovers after a period of adjustment.
• Algae Growth: In brighter lighting, algae can sometimes become an issue on the leaves, so regular maintenance and clean water are important.

Benefits in Aquariums:

• Aquascaping: It’s an excellent addition to aquascapes, particularly in low to medium-light setups. Its delicate appearance makes it a good plant for foreground or midground placements.
• Fish and Shrimp Friendly: Cryptocorynes are non-toxic to most fish and shrimp, making them an ideal choice for community tanks.
