Biotope Information

This biotope was designed to replicate the Pasir Panjang lakeshore area near Pangkalan Bun in Central Kalimantan, which hosts many endemic species. The water in this region is highly acidic and soft, with a dark blackwater coloration. In flowing areas, disturbed peat moss particles cause the water to appear cloudy. However, the shoreline section I recreated represents a calmer, low-flow zone where species preferring tranquil conditions are typically found. Species such as Sphaerichthys osphromenoides (Chocolate Gourami) and Parosphromenus spp. inhabit the shaded areas and cavities formed by roots and aquatic vegetation to avoid strong currents. Meanwhile, fish like Sundadanio axelrodi, Brevibora dorsiocellata, Trigonopoma pauciperforatum, and Desmopuntius Rhomboocellatus (Snakeskin Barb) are more adapted to swimming against the current but occasionally visit the shore to rest and graze on biofilm and algae. The biotope was inspired by underwater footage from the following videos: - https://www.youtube.com/watch?v=ID7Clj7__bc&t=1237s - https://www.youtube.com/watch?v=EvGe8V5K_Sw I also contacted the botanist scientist who filmed these videos to gather accurate information about the plant composition, local fauna, and water parameters of the region.
