Water temperature
15–26 °C
pH
6–8

Appearance and identification

Scissortail rasboras are slimmer and emphasize black-white tail markings.

Same-species behaviour

Keep at least 8–10; males maintain group hierarchies.

Space requirements

Use a 120 × 45 cm base.

Diet and feeding

Offer prepared foods with live or frozen supplements. It eats some algae but is no substitute for maintenance.

Compatibility limits

Constant activity and feeding competition can stress slow or timid companions; similar size alone does not make a good tankmate.

Aquarium environment

Flow and oxygenation may limit delicate planting; use suitable attached plants and leave open swimming space.
