Lighting: Provide moderate to high-intensity lighting to support healthy growth. LED lights or fluorescent tubes specifically designed for planted aquariums work well. Avoid using extremely bright lights as they can cause algae issues.

Substrate: Use a nutrient-rich substrate like aqua soil or a mixture of gravel and laterite. Cryptocoryne plants are heavy root feeders, and a good substrate will provide essential nutrients for their growth.

Water parameters: Cryptocoryne wendtii 'Brown' prefers slightly acidic to neutral water conditions. Aim for a pH range of 6.0-7.5 and a water hardness of 2-15 dKH. Maintain a temperature between 72-82°F (22-28°C).

Water movement: Cryptocoryne wendtii 'Brown' prefers gentle water movement. Avoid strong currents, as they can damage the delicate leaves.

Nutrients: Cryptocoryne plants benefit from regular fertilization. Consider using a comprehensive liquid or substrate fertilizer that contains essential macro and micronutrients. Supplementing with root tabs can also be beneficial.

CO2 supplementation: While not mandatory, adding carbon dioxide (CO2) to the aquarium can enhance the growth of Cryptocoryne wendtii 'Brown' and promote vibrant foliage. However, this plant can also thrive without CO2 injection.

Maintenance: Trim any damaged or decaying leaves regularly to maintain the plant's health and appearance. Cryptocoryne wendtii 'Brown' is a relatively slow-growing plant, so it won't require frequent pruning.
