Originating from Sri Lanka the Cryptocoryne petchii is a small plant with beautiful, slightly fluted leaf margins. The leaves become dark olive-brown with a violet underside. As with most crypts this plant needs little attention and will happily grow under low lighting.
Ideally place in the aquarium amongst rocks in clusters of two to three. This will create an 'all-natural' effect in your aquarium.
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.
