The melon barb (Haludaria fasciata) is a common species of cyprinid fish that is endemic to rivers in Goa, Karnataka, Kerala and Tamil Nadu in the Western Ghats of South India.

[1] They live in a tropical climate in water that typically has a pH of 6.0—6.5, a water hardness of around 5 dGH, and a temperature range of 22–26 °C (72–79 °F).

This species can also be found in the aquarium trade.

[3] The melon barb is an open water, substrate egg-scatterer, and adults do not guard the eggs.

[3] Males in breeding condition flush red and develop fine nuptial tubercles on their snouts, used for bumping and rubbing the females to induce egg release.
