CRYPTOCORYNE technical description and management (all varieties)

Name: Cryptocoryne

Family: Araceae


Origin and Habitat: Cryptocoryne comes from Southeast Asia, Sri Lanka and the New Guinea. They are made of many rhizomes from which start the leaves, there are many varieties, each with its different morphology, however, talking about this aspect, the most important feature is the ability to adapt, is an aquatic varieties resistant to all types of waters, alkaline and acid. In the aquarium, it can happen that the crypto lose all the leaves, and then regenerate from rhizomes in a totally different color. They change their appearance depending on the condition, for example, with so much light are darken and grow bushier and low, with no much light instead get longer and brighter. Cryptocoryne is a slow-growing variety and being from Araceae family like Anubias, are very similar but the main difference is that the cryptocoryne are not epiphytes, so you cant positioned on driftwood or rocks, they need for this reason a substrate. We usually use this plant in the middle of the tank, but in some case and some variety you can planting on the front of aquarium.

MVI_5140.MOV.Immagine012CRYPTOCORYNE BECKETII: Very similar to Petchii but in reduced form, about half, if kept well with a good light and nutrients becomes dark red almost reddish brown, even the leaf is reduced, not only the height.

Only when you buy you can see the difference; the leaf of red Wenditii has the tip more rounded, while the undulata has the pointed leaf.

Reproduction and moltipication: Remember that the rhizomes, to find nutrients moving under the sand, sometimes even along the whole tank and then leak out and give birth to a new plant, the same applies to the roots, with inert bottom develop more. At the time of planting it can be divided into 2 or 3 parts depending on the size.

Fertilizer and substrate: It is advisable to use gravelit, clay or porous stone as the first layer on the bottom, for better oxygenation and water flow, then a mineral rich and fertile substrate, we recommend fertilized sand but also inert okay. It can grow in the absence of CO2, but with proper emission of co2 and a strong light, the variety will grow faster, producing visible oxygen from leaves, the so-called pearling.
