My recent foray into Sumatra took me to various locations of wild fishes and plants through Central Sumatra. We travelled extensively and found that in some old locations, the wild Cryptocoryne Longicauda exposed in open areas in a drying stream due to land clearing for palm oil plantations. I amazed at the form of these plants adapting to such harsh environment. These plants grow best in shadier streams. The pH of the water is around 5.0. The base of the stream is sandy with cool water flowing through some sections.
