Sungai Kolok Floodplain, South Thailand

Sponsored by

Thailand, Ban Buketa, Narathiwat

This aquarium project is inspired by references such as Horst Linke’s Labyrinth Fish World and Rodrigo Silva’s videos, seeking to recreate a flooded biotope typical of the Southeast Asian rainy season. The habitat is characterized by whitish waters, leaf-covered soils, and abundant organic matter. The scene is structured around reeds and plant debris, with no rocks, faithfully reflecting the natural landscape.

A clay substrate with a thin layer of neutral sand was used as a base for the plants. Twelve Murdania keisak plants were added as the dominant species, along with floating plants such as Salvinia and Lemna minor, which provide shade and shelter.

The selected fauna includes fish from the anabantid group, such as Betta imbellis, adapted to acidic and poorly oxygenated waters, as well as companion species such as Boraras maculatus and microinvertebrates. The setup seeks to replicate a functional and seasonal, naturalistic, and specific ecosystem.

Aquarium decoration

This project utilized a variety of natural materials to recreate a realistic aquatic environment, inspired by flooded tropical habitats. The base of the landscape was built using dried reeds and cane leaves, arranged organically to simulate the natural accumulation of plant debris in floodplain areas. These elements add texture, provide shelter, and evoke the distinctive visual character of a puddled, debris-strewn bottom.

Fine-grained brown sand was used as the substrate, replicating the soft, organic-rich soil typical of such environments. Floating plants such as Salvinia sp. and Lemna minor were incorporated to shade the water column and reproduce the natural surface vegetation cover.

Together, these materials create a cohesive and functional aesthetic that enhances both the visual authenticity of the aquascape and the well-being of its aquatic inhabitants.

Aquarium equipment
  • Lighting: Chihiros Series B
  • Tank: Kryoscape
  • Filter: Sicce Whale 120
Fish care

Create an ideal aquarium for them by providing ample shelter and environmental enrichment. Feed live food frequently to promote better health and encourage natural behaviors. Additionally, maintain the tank properly to establish and preserve optimal water parameters.

Fish list:

  • Boraras maculatus (Cyprinidae)
  • Betta imbellis (Osphronemidae)

Crustaceans:

  • Limnopilos naiyanetri (Hymenosomatidae)

 

Plant care

The plants used help absorb excess nitrates and phosphates from the water column and require little to no fertilization. Appropriate lighting is provided to support healthy photosynthesis.

Wetland plant list:

  • Lemna minor (Araceae)
  • Salvinia sp. (Salviniaceae)
  • Murdannia keisak (Commelinaceae)
Water care

A 20% water change is performed weekly, with a 50% change every three weeks. The glass is cleaned once a week, and excess organic matter is removed using a gravel vacuum. Mechanical equipment is cleaned every two months.

Greg Martin: A nice, mature entry. I couldn’t see any Crypts in the BAM photos and that was an important part of the BIN.
