Small Stream in Mandor Town, West Kalimantan, Indonesia
Indonesia, West Kalimantan, Mandor
The Kapuas River (or Kapoeas River) is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1.143 km (710mi) in length, it is the longest river in the island of Borneo and the longest river in Indonesia and one of the world’s longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta. The delta is located west-southwest of Pontianak, the capital of the West Kalimantan province.
This Kapuas River should be distinguished from another Kapuas River, which starts on the other side of the same mountain range in central Borneo but flows to the south, merging with the Barito River and discharging into the Java Sea.
The area whose biotope I sampled is a small stream in the town of Mandor in West Kalimantan. It is a region where species such as Betta mandor and Betta brownorum are endemic.

- Surrounding area
An area full of small flood ponds and small slow-flowing streams located within the Kapaus River basin. Mandor town is in West Kalimantan province. In this area where Betta mandors live, streams suitable for them flow through forest areas.
- Underwater landscape
Since there are so many trees around the area, the underwater landscape is full of drying leaves, tree branches and submerged young tree trunks. There is white sand on the ground. The water looks like blackwater because it is stained with tannins.
Fishlist:
- Betta mandor (Osphronemidae)
- Betta brownorum (Osphronemidae)
Wetland plants:
Aquatic plants:
- Cryptocoryne sp. (Araceae)
- Threats to ecology
The region is heavily affected by agricultural and industrial activities, and the habitats of species such as mandor and brownorum are shrinking day by day. Problems of access to clean water and exposure to chemicals are increasing for living creatures in the region.

Comment by the expert
Heiko Blessin:
Heok Hee Ng: Reasonably accurate descrioption of a heath forest-type habitat. The pH of the water should be a little lower (around 4–5) for such a habitat. There are other fish species found in the habitat (the linked video shows at least some kind of Pangio being caught).
Greg Martin: Well researched.
