Cryptocoryne

provided by wikipedia EN

Cryptocoryne is a genus of aquatic plants from the family Araceae. The genus is naturally distributed in tropical regions of India, Southeast Asia and New Guinea.[1]

The typical habitats of Cryptocoryne are mostly streams and huge rivers with not too rapidly flowing water, almost grow in the virgin forest(Including semi virgin forest). They also live in seasonally inundated forest pools or on river banks submerged only at high water.

The first Cryptocoryne species was described in 1779 as Arum spirale by Retzius.

Cultivation and uses

Some Cryptocoryne is popular commercially cultivated aquarium plants. Submerged plants reproduce vegetatively, emerse plants may flower and reproduce sexually. Many species are cultivated only by dedicated experts and are very hard to grow, or are not present in a culture at all. Some species are endangered because their natural habitats are disappearing.

Cryptocoryne is either found in peat bogs or on limestone; the latter do well in most aquaria, the former must have soft water to survive and need decomposing beech leaf litter to do well. C. striolata while found primarily in peat bogs has also been found growing on limestone. Borneo is home to many endemic crypts previously thought to grow only in tea-colored soft acid water emulating peat bogs but exploration of habitats from 2005 to 2010 showed about half grew on limestone. These hardwater Cryptocorynes are generally the easier ones to keep (in fact, some species, such as Cryptocoryne wendtii are said to be among the most versatile of aquarium plants); they tolerate low or bright light but grow faster in more intense light,This water plants range of around 12 to 33 °C, and slightly alkaline to neutral pH.

Plants of the genus Cryptocoryne, which range from India to New Guinea are found in very diverse conditions. Some are true acid loving plants such as C. pallidnerva, found in peat bogs in Borneo, while others such as C. crispatula var. balansae and C. pontiderifolia are found in streams with limestone beds—hard alkaline water. One species, C. ciliata is even found in semi brackish water in some areas. It is one of the few aquarium plants that tolerates salt concentrations.

Cryptocoryne plants have been in cultivation in the aquarium hobby since the late 18th century, although it was not until the 1960s that more than a handful of species was known and became more common in the hobby. New species still regularly crop up as interest in these plants widens and more collecting expeditions by private parties are carried out.

Crypt melt

A phenomenon often encountered when planting new crypts in an aquarium is commonly called Crypt melt, whereby the plant loses all its leaves.[2] There seem to be two possible causes for this.

Rapid environmental changes is thought to trigger this, as these plants don't seem to adapt well to transplantion, and may need 30 days or so to become established and for the leaves to regrow. Experienced growers report that it is better to plant crypts in aquariums that have been established for at least three months.

In the wild, Crypts can grow fully submerged underwater, but in some plant nurseries they are often grown emersed and crypt melt could then be triggered by the change from emerse to submerse conditions.

There is lately a trend for such nurseries to send crypts as just a rootstock (i.e. without the leaves) to reduce shipping costs and because the leaves will be lost anyway once planted in an aquarium.

Other reports[3] emphasise the need to change the aquarium water regularly to prevent the buildup of nitrates which are thought to trigger this condition (often referred to as a disease)
