- Use fine sand as a substrate or use smooth gravel because sensitive barbels can be hurt by sharp gravel.
- Plants, as well as driftwood, should be added so that they can have hiding spots and the tank can have a natural look.
- Moderate lighting works best. Shaded areas are preferred.
- A gentle filter keeps the water clean without the creation of strong currents.
