3. In the Wild
While specific information on Cryptocoryne beckettii ‘Petchii’s’ precise wild origin is less detailed than some other Cryptocoryne varieties, its parent species, Cryptocoryne beckettii, originates from Sri Lanka. Cryptocoryne plants, in general, are found in slow-moving or stagnant waters, often in shaded areas of rainforests. They are known for their ability to adapt to varying water parameters, including periods of submergence and emersion, which contributes to their hardiness in the aquarium. The ‘Petchii’ variant is likely a cultivated form selected for its desirable color and growth characteristics.
4. In the Aquarium
Cryptocoryne beckettii ‘Petchii’ is a true showstopper in the aquarium, despite its relatively compact size. Its lanceolate leaves typically display a dark green to brownish-green on the upper surface, but it’s the stunning purplish-red underside that truly makes it pop, especially when viewed from different angles or in tanks with good lighting. This contrast provides a beautiful visual dynamic, adding depth and warmth to your aquascape.
Given its moderate height (10-20 cm), ‘Petchii’ is perfectly suited for the foreground of larger aquariums or the midground of smaller tanks. Planted in groups, it can create a dense, colorful carpet or a vibrant bush-like effect, providing excellent cover for smaller fish and invertebrates.
Cultivating ‘Petchii’ is straightforward, making it an ideal choice for beginners. A nutrient-rich substrate is highly recommended, as Cryptocorynes are heavy root feeders and will benefit immensely from nutrients directly accessible to their root system. While CO2 injection is not strictly necessary, providing it can significantly boost growth rates and intensify the rich coloration, particularly the purplish-red tones.
Lighting plays a crucial role in bringing out the best in ‘Petchii’. Under moderate to high lighting, the vibrant purplish-red hues will be more pronounced. In lower light conditions, the plant will still grow, but the coloration may be less intense, appearing more greenish-brown.
One of the most appealing features of Cryptocoryne beckettii ‘Petchii’ is its resilience. It’s known for being less prone to the infamous “crypt melt” that can sometimes affect other Cryptocoryne species when environmental conditions change rapidly. This makes it a robust and reliable choice for a stable aquascape.
Propagation is simple and happens naturally through runners. These side shoots will emerge from the main plant, developing into new plantlets that can be gently separated and replanted elsewhere to expand your patch of ‘Petchii’ or shared with fellow hobbyists.
5. My Observations
In my experience, Cryptocoryne beckettii ‘Petchii’ is an exceptionally rewarding plant. Its modest size makes it versatile for various tank dimensions, and its distinctive coloring truly adds a touch of elegance. I’ve noticed that while it’s tolerant of a range of conditions, giving it a good substrate like aquasoil and moderate lighting really makes its colors explode. The subtle ripple in its leaves, combined with the two-tone coloration, creates a very natural and appealing texture in the aquascape. It’s a “set it and forget it” kind of plant once established, requiring minimal fuss but consistently delivering beauty. For anyone looking for a low-maintenance plant with a big visual impact, Cryptocoryne beckettii ‘Petchii’ is an absolute winner.
