Originating from the Central highlands of Sri Lanka the Cryptocoryne parva grows in dense colonies along the banks of fast flowing rivers. Known as the Green Water Trumpet, this delightful little crypt is one of the smallest of the species, growing slowly this plant is rather demanding needing high light and CO2 levels.
This plant looks great planted in a group of three or four and amongst light rocks or wood.
Understanding Crypt melt - all Cryptocoryne species require stable water parameter and light conditions. Once planted, Crypts should not be moved otherwise it can trigger what is called Crypt melt. If a Crypt has a significant change of environment (ph, kh , gh, lighting intensity or duration, root disturbance etc), Crypt melt can be triggered. The leaves start to disintegrate as the plant prepares for its new environment - DO NOT WORRY! Your plant will begin to grow back over the next 30 days (sometimes sooner, sometimes later) - it's still very much alive and busy getting ready for the growth of new leaves. In the meantime, any decaying leaves should be trimmed and recycled in a compost bin.
