Met this local guy(Haji Badaruddin) and we followed them for a betta field trip collecting crypte off Serian, a small town call Balai Ringin. It is said to have Brownorum but we didn't catch any. We proceed to this place in Serian to collect Betta Taeniata up a waterfall! Surprising to have a betta in this part of the waterfall which I estimate at least 500m from ground level. We had to climb a foothill which obviously were use by the locals before.
Got about 3 pieces of Betta Taeniata,
