Expert Tips
Cryptocoryne affinis is one of the most reliable and forgiving aquarium plants, making it perfect for beginners or low-tech setups. Plant individual crowns in nutrient-rich substrate, spacing them a few centimeters apart to allow room for growth. The plant will gradually spread through runners to form attractive clusters. Be patient during the initial establishment period - Cryptocorynes may experience "crypt melt" when first introduced to new conditions, where leaves dissolve. This is normal; simply maintain stable water parameters and the plant will regrow from healthy roots.
This species thrives in low to medium light and doesn't require CO2 injection, making it ideal for shaded areas and low-tech aquariums. The slow to moderate growth rate means minimal trimming is required once established. Cryptocoryne affinis is extremely adaptable to various water parameters and can tolerate a wide range of conditions. The attractive dark green to brownish coloration develops best under moderate lighting with regular fertilization, particularly root tabs. Avoid frequent replanting or major changes to water parameters, as Cryptocorynes prefer stable conditions. Propagation occurs naturally through runners that produce daughter plants - these can be separated once they develop their own root system. This versatile plant works beautifully in nature aquariums, community tanks, and as a reliable foreground to midground feature in various aquascaping styles.
All plants are shipped carefully packaged to ensure they arrive in excellent condition. Live plants may vary slightly in size and colour from photos. Supplied as a single plant.
Acclimation: Float the bag in your tank for 15 minutes to equalise temperature, then plant directly in substrate.
Lighting: Most aquatic plants thrive at 0.5+ watts/litre with 6500K colour temperature for 6-8 hours/day.
Fertilising: Use a quality liquid fertiliser weekly. Root tabs help heavy root feeders.
CO₂: While not essential for most plants, CO₂ injection dramatically improves growth and colour.
Trimming: Regular trimming encourages bushy, healthy growth and prevents shading of lower leaves.

Most of our aquarium plants are grown submerged (underwater), which means they adapt faster to your tank and are less likely to melt. This gives you stronger roots and instant success. The exception is our terrarium plants, which are grown emersed (above water)
