Sawbwa resplendens Asian Rummynose Rasbora

The Asian Rummynose Rasbora (Sawbwa resplendens), also called the Burmese Rummynose or Rummynose Rasbora, is a small freshwater fish native to the Inle Lake region of Myanmar. Mature males are known for a silvery body, red nose, and contrasting blue markings near the tail; females are generally less colorful. This peaceful, active species is best kept in a group in a mature aquarium with stable, cooler-to-moderate water conditions.

Species distinction: This Asian fish is not the South American Rummy Nose Tetra. Despite their similar common names, they are different species with different water requirements.

Aquarium Setup and Grouping

Provide a fully cycled, well-filtered aquarium with live plants, open swimming areas, gentle-to-moderate flow, and stable water conditions. A suitable group helps the fish feel secure and display natural social behavior. Keep enough cover to reduce stress without overcrowding the swimming area.

Tankmates and Shrimp Compatibility

Choose peaceful, similarly sized fish that tolerate the same cooler, neutral-to-alkaline water conditions. Some compatible ricefish and other small community fish may be suitable after checking their individual requirements. Avoid aggressive species and tropical fish needing constantly high temperatures. Adult shrimp may coexist, but very small shrimplets can be eaten.

Feeding

Offer fine flakes, suitably sized micro pellets, and occasional small frozen or live foods such as baby brine shrimp, daphnia, and cyclops. Feed modest portions and ensure all individuals can access the food.
