- Water temperature
- 20–27 °C
- pH
- 6–7

Same-species behaviour
Keep at least 8–10.
Space requirements
Allow a 60 × 30 cm base.

Assess predation, feeding competition, space and water for companions.
Aquarium environment
Planting and a dark substrate reveal the sheen; retain swimming space and oxygenation.
