Aquarium Biotope Wizard
Answer a few quick questions and discover a real freshwater habitat you can recreate at home — complete with water parameters, substrate, hardscape, planting plan and stocking guidance.
About Biotope Aquariums
A biotope aquarium recreates one specific wild habitat as faithfully as possible. Instead of mixing fish and plants from different continents, every choice — water chemistry, substrate, hardscape, planting and stocking — is drawn from a single real location, so the finished tank works as an accurate model of a river, lake or swamp rather than a general display.
This wizard covers habitats across South America, Africa, Asia, Australasia and Central America, from Amazon blackwater and Congo rapids to the rocky shores of Lake Malawi and Lake Tanganyika, Southeast Asian forest streams, Borneo peat swamps and Australian billabongs. Each result gives target water parameters, a substrate and hardscape plan, a matching plant palette, stocking suggestions drawn from species genuinely recorded in that habitat, and a difficulty rating.
In-Depth Biotope Guides
Once the wizard has pointed you at a habitat, these guides go deeper on the water chemistry, hardscape and stocking behind the most popular biotopes in the hobby:
- Blackwater Aquariums — tannin-stained, soft acidic water built on leaf litter, botanicals and driftwood
- Southeast Asian Biotope — shaded forest streams and peat swamps, home to rasboras, bettas and licorice gouramis
- West African Aquariums — river and stream habitats spanning soft blackwater to brisker, plant-rich reaches
- Lake Malawi — hard alkaline Rift Lake water over rocky mbuna reefs and open sand flats
- Lake Tanganyika — the hardest, most alkaline Rift Lake, with shell beds, rubble zones and steep rocky shores
If you're planning the physical build alongside the habitat research, the Tank Volume & Substrate Calculator works out water volume and how much substrate you'll need, and the aquascaping guide covers layout styles and hardscape materials in more depth. For terrestrial setups, try the Terrarium Build Wizard instead, and browse Club Resources for the full library.
Frequently Asked Questions
Common questions on planning and stocking a biotope aquarium.
What is a biotope aquarium?
A biotope aquarium recreates one specific wild habitat as faithfully as possible — the water chemistry, hardscape, plants and fish are all drawn from the same real location, rather than mixing species and decor from different parts of the world.
How is a biotope aquarium different from a normal community tank?
A community tank mixes fish and plants from anywhere, chosen for compatibility and looks. A biotope restricts every choice to species that genuinely occur together in one habitat, so the tank doubles as an accurate model of a real river, lake or swamp.
Is a biotope aquarium harder to keep?
Not necessarily. Some biotopes such as a Southeast Asian stream or an Australian billabong are very beginner friendly, while blackwater and Rift Lake setups such as Lake Malawi and Lake Tanganyika need tighter control of pH and hardness. Difficulty depends on the habitat you pick, not on the biotope approach itself.
What is a blackwater biotope?
Blackwater habitats such as the Rio Negro carry tannins leached from leaf litter and wood, staining the water tea brown and driving pH low and hardness very soft. In the aquarium the look is recreated with botanicals, leaf litter, driftwood and dim lighting — our blackwater aquariums guide covers the water chemistry and botanicals in detail.
Do I need live plants in a biotope aquarium?
Only if the real habitat has them. Many authentic biotopes — Rift Lake rocky shores, blackwater leaf litter beds and fast rapids among them — are naturally almost plantless, so hardscape, substrate and botanicals do the work instead.
