Essential Equipment Checklist

Tank Selection

Size: Choose at least a 80-120L (20-30 gallon) aquarium for ample swimming space and aquascaping room.
Shape: Long, rectangular tanks best mimic stream beds.

Filtration System

External canister filter: Powerful yet gentle flow for crystal-clear water
Sponge pre-filter: Protects small shrimp and fish fry

Lighting

High-quality LED lighting system with a color temperature of 6000K-8000K to mimic daylight
Consider timers for consistent photoperiods (8-10 hours/day)

Heater (If Needed)

Set between 22-26°C (72-78°F) for tropical Southeast Asian species

CO₂ Injection (Optional)

Beneficial for demanding aquatic plants but not essential for low-tech setups

Substrate & Hardscape Materials

Substrate

Sandy substrate: Natural river sand or fine gravel base layer
Nutrient-rich substrate: Use as underlayer for planting zones

Stones & Wood

Smooth river stones and pebbles (varied sizes for a natural look)
Driftwood (e.g., malaysian driftwood or spiderwood) for fallen branch effect

See our guide on aquascape hardscape ideas to perfect your layout.

Plant Selection: Native Flora for Southeast Asian Streams

Successful aquascaping is rooted in plant choice. Southeast Asian streams typically feature:

Cryptocoryne species (C. wendtii, C. balansae) – lush midground foliage
Blyxa japonica – grassy texture for banks
Limnophila sessiliflora – feathery background
Bucephalandra – unique epiphyte attached to wood/rock
Java fern (Microsorum pteropus) and Anubias – easy, shade-loving options

Fish & Invertebrate Stocking List

For a true-to-life biotope, focus on peaceful, stream-dwelling species:

Harlequin rasbora (Trigonostigma heteromorpha)
Chili rasbora (Boraras brigittae)
Zebra danio (Danio rerio)
Kuhli loach (Pangio kuhlii)
Shrimp (e.g., Amano, Blue Velvet)
Snails (Nerite or horned snails for algae control)

See beginner-friendly fish for planted tanks for more species ideas.

Water Parameters & Maintenance

pH: 6.0 – 7.0 (slightly acidic to neutral)
KH: 1–5 dKH
Regular water changes: 15-25% weekly to maintain clarity & stability
Monitor ammonia, nitrite, nitrate for a healthy cycle
Test parameters monthly, or as needed

Aquascaping Layout Tips

Layout the hardscape with a “flowing” riverbed effect
Create a natural “stream bank” with larger stones and driftwood on the sides
Plant denser vegetation at the edges to mimic riparian growth
Leave open sandy or pebbly areas to replicate stream channels

Southeast Asia Stream Setup: Step-by-Step Checklist

Plan your design based on research and biotope examples.
Thoroughly rinse all substrate, stones, and décor.
Add substrate layers (nutrient first, then sand/gravel on top).
Arrange stones, driftwood, and hardscape for a stream effect.
Fill tank halfway with dechlorinated water (add hardscape as needed).
Carefully plant Crypts, Blyxa, Java fern, etc.
Finish filling tank; set up heater, filter, lights, and CO₂ system (if used).
Cycle the aquarium completely before adding livestock.
Stock with compatible Southeast Asian fish and shrimp.
Maintain with regular pruning, water changes, and parameter checks.

Common Mistakes to Avoid

Skipping the cycling process or overstocking too soon
Mixing incompatible or non-native species
Using unnatural décor (bright gravels, plastic plants, etc.)
Neglecting plant nutrients or CO₂ in high-light setups
