Amazon Soft Water Community
A warm, soft-water South American community combining colourful tetras with peaceful bottom dwellers. Ideal for aquarists wanting natural behaviour and cohesive environmental requirements.
Stocking Plan
| Species | Recommended Count | Compatibility Links |
|---|---|---|
 Cardinal Tetra Paracheirodon axelrodi | 10–15 | |
 Corydoras Corydoras spp. | 6–8 | |
 Ram Mikrogeophagus ramirezi | 1–2 |
Why This Setup Works
This combination works because:
- •Shared water parameters: pH overlap around 6.0–7.0, hardness overlap in soft → soft.
- •Size compatibility remains stable (3.5–7.0 cm), with no large predatory gap.
- •Behaviour balance is calm: temperament overlap is peaceful across the group.
- •Feeding needs span multiple diet groups; a split feeding routine keeps all species covered.

Equipment Checklist
- • Tank: 80 L or larger
- • Heater: 100W class
- • Filter: Sponge or internal filter with gentle flow
- • Substrate: Fine sand to protect barbels
- • Plants: Low-maintenance planting for cover and stress reduction
Common Mistakes With This Setup
- • Adding full stock before the tank is fully cycled
- • Introducing schooling species in undersized groups
- • Keeping corydoras in groups that are too small
- • Overfeeding mixed communities instead of split portioning
