pH
5.5–7.5
Hardness

Appearance and identification

The pointed, somewhat conical head distinguishes it from blunt-headed relatives. Males are usually larger with longer fins.

Social behaviour and territory

For breeding, prefer a naturally formed pair. 80×30 cm suits one pair; groups need a larger aquarium.

Diet and feeding

Try suitably sized dry food, alternating with live or frozen foods such as Daphnia and brine shrimp. Feed small portions and avoid overfeeding.
