Who this list is for
A blackwater-style tetra aquarium starts with a calm, covered freshwater setup and materials such as driftwood, leaves, and cones. This list is for compatible tetra species indoors; research the chosen fish before adjusting water conditions.
How to use this list
Start with a 20-gallon long aquarium or larger and a tight-fitting lid. Install the low-flow sponge filter with the air pump, airline tubing, and check valve, then add the adjustable heater and digital thermometer. Use aquarium-safe water conditioner and the freshwater liquid test kit while preparing the aquarium. Add fine dark sand, natural driftwood, Indian almond leaves, aquarium-suitable alder cones, floating plants, and low-light aquarium plants. Use the leaf-litter collection bag for the listed natural materials, then set the dim light and timer.
Common mistakes
Do not collect or add leaves and cones without confirming they are suitable for aquariums; this list specifically names Indian almond leaves and suitable alder cones. Avoid strong filtration or bright lighting in place of the low-flow sponge filter and dim light. Do not assume all tetra species share identical requirements.
What is on this list
The list includes the long aquarium, lid, filtration, aeration, heater, temperature and water-testing tools, dark substrate, wood, leaves, cones, plants, lighting, net, and aquarium-only bucket. Cross off compatible gear you already own.
Before you go
Confirm the footprint for a 20-gallon long tank and make sure the lid, filter, and light fit together. Select the tetra species first, then research its needs before choosing how to use the natural materials and adjust water conditions.
