Went to Berjaya Hill Bukit Tinggi last weekend. Saw some nice moss at the Japanese theme garden. There are different types of moss, but I just took photo of this which I believe can be grow submerge. Not sure if it is Java moss or Singapore moss though.
big patch under trees. I found them in a near by jogging park in some cooler/shade area too. Look like temperature play a big part in growing them.
