Southeast Asian Blackwater Pool Biotope Aquarium Setup


A biotope aquaria is an aquarium that is set-up to simulate a natural habitat. The fish, plants, water chemistry, and furnishings are similar to those that can be found in a specific natural setting.

Always check compatibility! Some species from a particular habitat are not suitable tankmates. For example, the Peacock Bass will eat small tetras since they are their natural food in the wild.

The biotope aquarium can be adapted by adding species from disparate areas that have similar water requirements.

Southeast Asian Blackwater Pool

Creeks and streams originating from deep in the rainforest are often blackwater.
With decaying plant vegetation and few, if any, mineral sources, the water is acidic and very soft.
This environment provides a home to many species of plants and fish.

pH 5.5-6.5, 0-4 dH, 81-84 F (27-29 C)

The tank should be densely planted with a fine gravel or clay substrate.
Use wood to create hiding places and use peat filtration.
There should be little surface current.

Cryptocoryne, Nymphaea, Eleocharis

Gouramis, Bettas, Rasboras, Loaches, Glass Catfish, Cyprind sharks, Flying Fox
