Small blackwater stream in Lalang Tanjung

Sponsored by

Indonesia, Riau Province, Lalang Tanjung

This biotope aquarium was inspired by the small stream in Lalang Tanjung, Riau. The body of water from Sungai Tohor runs across the forest in Lalang Tanjung. The trapped water, often close to the villagers, creates a small blackwater stream. This water is acidic contains decomposing materials from leaf litters, branches and also peat materials. The inhabitants found here, adapted to a low pH water parameter, typically are Rasboras, Bettas and some Gouramis.

Aquarium information

Aquarium description

Set-up date
July 2021
Aquarium decoration

Cocopeat substrate, leaf litters consisting of Nipa palm, Angsana, Macarranga and Cattapa from the site and few branches from the site, as well.

Aquarium equipment

JEBO 501 Hang on filter and Kandilla S-200 light.

Fish care

Fish: Sphaerichthys osphromenoides and Rasbora einthoveinii.

Rasbora einthoveinii is an easy-to-care fish; they can withstand a wide range of water parameters, but they do best in slightly acidic water. The Chocolate gourami, on the contrary, can only be kept in water with low pH, between 4.0-6.0. Unlike the Rasbora, they are fed with daphnia and sinking fish food.
