Cryptocoryne Undulatus Brown is a delightful looking plant with glossy brown pointy leaves and fine dark stems. This is a familiar plant with Aquascapers as they can be used as a foreground plant when creating a sandy foreground which is particularly popular at the moment in aquascaping.
As with most crypts this plant needs little attention and will happily grow under low lighting.
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.
