Description

Crypt Sri Lanka is a less common type of crypt that comes from Sri Lanka as the name implies. These plants were originally found in fast-flowing limestone bed streams or rivers. They need high levels of calcium to thrive in a tank environment, as well as CO2, phosphate, iron, and nitrate. Although they are easier to grow submersed, they will also grow emersed and can produce flowers above the water. They can be planted into the substrate or attached to a rock or piece of driftwood with a cotton thread or fishing wire.

As with all crypts, it can be sensitive to changes in water parameters and doesn't like to be moved. It is normal for the plant to undergo “crypt melt” when introduced to a new tank, or if water conditions change too much. If this process begins, you can cut away any melt and attempt to stabilize the water. They should produce new growth once they have acclimated. These plants will also melt if the lighting is too strong. Moderate to low lighting is sufficient for this plant.

C. Sri Lanka propagates through runners, which can be cut and replanted into the substrate if desired. For good coverage, plant individual stems about one inch apart. Water trumpets can also be planted in bunches as long as all the roots have exposure to nutrients from the substrate.
