Creek, Phong Nha-Ke Bang National Park, Vietnam
Viet Nam, Phong Nha-Ke Bang National Park, Quang Binh Province
A fragment of a creek from the Son River, near the world’s largest and most powerful Son Doong Cave in Phong Nha-Ke Bang National Park, Vietnam, inspired me to create a biotope for Macropodus opercularis, which inhabits this area.
The creek is characterized by numerous roots of emersed and floating vegetation that provide safe hiding spots for Macropodus opercularis and its fry. A small stream flows over a sandy bottom scattered with small stones nestled between larger rocks. The substrate contains many dry leaves and dried fruits, contributing organic compounds such as tannins and humic substances. Delicate lighting, sufficient for the local plants, helps recreate the unique atmosphere of this habitat.

- Surrounding area
The creek is surrounded by dense vegetation, including trees, tall grasses, and a variety of plant species. Leaves and dry branches often fall into the water or remain partially submerged, creating a beautiful above-water landscape. A dense growth of water lilies is found in abundance, along with a few other floating plants that provide excellent hiding spots for the fish and their fry.
- Underwater landscape
The watercourse in the area contains a large amount of both submerged and emersed vegetation. The underwater landscape features numerous water lilies, some moss, and organic debris that has accumulated on the roots of floating plants and along the bottom.
This material supports a thriving community of microorganisms, which in turn provide a food source for fish fry in a natural symbiotic relationship. The substrate is also populated with a variety of aquatic plants. Along the shoreline, fallen leaves and broken tree branches create a striking and natural underwater scene.
