Cryptocoryne wendtii 'Long'

Notes: 

Many hobbyists who first get Cryptocoryne wendtii into their aquariums will see a sudden deterioration in the plant and may think they have somehow killed it, even while other plants are thriving. It is important to keep in mind that these plants, while easy to maintain and grow once established, are finicky about changing conditions. Any sudden or drastic change in their surroundings can trigger this mysterious crypt melt. While the plants may seem to have suddenly died, a little patience by the hobbyist will shortly be rewarded by new leaves coming up from the otherwise healthy plant's roots.

Description: 

Native to the island of Sri Lanka, Cryptocoryne wendtii is one of the most common and widely used aquarium plants available today. It is also one of the most variable species, with several color variations including reds, browns, greens, and several mixes of those. To add to the variety, the texture of the leaves can vary greatly within the species, as can the leaf size, ranging from 5 to 18 inches.
