- Maintain clean, well-oxygenated water with stable parameters
- Perform regular partial water changes (20–25% weekly) to prevent ammonia and nitrate buildup.
- Use fine sand or smooth gravel substrate to protect delicate barbels from injury.
- Avoid overfeeding; uneaten food can decay quickly and harm water quality.
- Keep in groups of 6+ to reduce stress and encourage natural behaviour.
- Provide hiding spaces (driftwood, plants, caves) to mimic their natural habitat and lower anxiety.
