General Description
Cryptocoryne parva, also known as the dwarf water trumpet, is the smallest species within the water trumpet group. Originating from the central highlands of Sri Lanka near Kandy city, it forms dense colonies along riverbanks. While it has become scarce in the wild and potentially endangered, it is readily available in the aquarium trade due to its slow growth rate. This plant closely resembles Cryptocoryne x willisii but remains smaller under similar conditions. Initially confused with Cryptocoryne nevillii, it is now recognized as a distinct species.
Aquarium Suitability
Cryptocoryne parva is suitable for aquariums due to its slow growth and small size, making it ideal for nano tanks and foreground planting. It requires ample light, carbon dioxide, and nutrient-rich substrate or fertilization for optimal growth. It is essential to maintain adequate levels of iron and potassium to prevent deficiencies like chlorosis. Propagation is achievable through lateral shoots on the rhizome and runners, especially in emersed conditions.
Demands and Hardiness
The demands of Cryptocoryne parva in aquariums include a medium to high level of light, carbon dioxide levels ranging from 5-40 mg/l, and a pH range of 5-8. It thrives in temperatures between 23-26°C and tolerates temperatures from 15-28°C. The plant requires a nitrate concentration of 10-50 mg/l, phosphate levels of 0.1-3 mg/l, and potassium levels between 5-30 mg/l. It is not suitable for outdoor use in colder climates.
Aquascaping & Usage
In aquascaping, Cryptocoryne parva can create a grass-like lawn effect, making it suitable for foreground or ground cover in group plantings. Its slow growth rate contributes to easy maintenance, particularly in small aquaria and nano tanks. With proper care and patience, it can develop into a lush carpeting of vegetation, enhancing the aesthetic appeal of the aquarium.
Propagation
Cryptocoryne parva propagates by forming lateral shoots on the rhizome and producing runners, which grow faster in emersed conditions. Propagation can also be achieved through methods like splitting, cutting off daughter plants, and rhizome division. Patience and providing the necessary environmental conditions are key to successful propagation of this species.
Habitat and Distribution
In its native habitat of Sri Lanka's central highlands, Cryptocoryne parva thrives in dense colonies along riverbanks. Although once common in the wild, it has become increasingly scarce, possibly classifying it as an endangered species. The plant's distribution has been limited mainly to the aquarium trade and hobbyist exchanges, ensuring its availability for enthusiasts worldwide.
