Appearance and identification

Gill-cover bars may be pale or lack color in some populations; red bars alone do not identify it.

Social behaviour and territory

Several males may be tried with abundant cover and broken lines of sight. A single pair is preferable for breeding; 45×30 cm suits them.

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.
