This biotope aquarium models the habitat of Rasbora sp., a fish native to the streams of Aik Seruk, Sijuk District, Belitung Island, Indonesia. This species is endemic to and thrives throughout Belitung Island.

I am particularly captivated by this fish due to its exotic nature and status as a dominant species across most freshwater streams on the island. Its unique appeal gives it significant potential as an ornamental fish from Indonesia.

In addition to Rasbora sp., this biotope aquarium also houses Striuntius lateristriga and Pristolepis grootii.

Aquarium information

Aquarium description

Set-up date
March 2025
Aquarium decoration

I used river stones sourced directly from the location and incorporated roots and branches to replicate the natural habitat. For the aquarium background, I used river-themed art print paper. The lighting was arranged to create an effect reminiscent of sunlight filtering through river water.

Aquarium equipment
  • Spotlight Kandila 1M is used to create a sunlight effect. The gutter filter is filled with sponge and synthetic cotton.
  • Pump engine: Takari 1800, 1600 L/h, 30 Watts.
  • Wave Maker: Recent AA WM 24000, 24,000 L/h, 25 Watts, used once a week for a short period on fast water mode.
  • Additionally, Kandila S500 and Spotlight Kandila S200 are used to enhance the sunlight effect.
Fish care

I feed the fish daily with small worms and an appropriate amount of fish pellets. The aquarium provides ample space for swimming and feeding. Additionally, I have created crevices that serve as nesting and spawning sites for all the fish in the tank.

Fish list:

  • Striuntius lateristriga (Cyprinidae)
  • Pristolepis grootii (Pristolepididae)
  • Rasbora cf. patrickyapi (Danionidae)
Plant care
Water care

20% water change once a week.
