Melon Barb
Haludaria fasciata
📍 South Asia (Southern India)
The Melon Barb (Haludaria fasciata) is a colorful and active schooling fish native to the rivers of southern India, displaying attractive reddish-orange and black banding reminiscent of a melon's stripes. They are a hardy and relatively peaceful species well-suited for community aquariums with similarly sized tankmates. Their vibrant coloration intensifies in well-maintained water conditions and when kept in proper schools.

Care Guide
Diet
Melon Barbs are omnivores that thrive on a varied diet including high-quality flake or pellet foods as a staple. Supplement regularly with live or frozen foods such as bloodworms, daphnia, and brine shrimp to enhance coloration and vitality. Feed small amounts 2-3 times daily, ensuring all food is consumed within a few minutes to maintain water quality.
Behavior
Melon Barbs are active, energetic schooling fish that do best in groups of six or more, which helps reduce fin-nipping tendencies toward tankmates. They spend most of their time in the middle water column, swimming actively throughout the tank. While generally peaceful within a community, they can occasionally nip at long-finned or slow-moving fish, so tankmate selection should be considered carefully.
Breeding
Breeding Melon Barbs is moderately straightforward and follows typical egg-scattering barb behavior. Condition a pair or group with live and frozen foods, then move them to a separate breeding tank with fine-leaved plants or a spawning mop and slightly softer, warmer water around 26°C. Parents will scatter adhesive eggs and must be removed promptly after spawning to prevent predation; eggs typically hatch within 24-48 hours.
Tank Mates
Peaceful barb of similar size that shares compatible water parameters and activity level
Active schooling barb that coexists well; avoid long-finned varieties due to potential nipping
Peaceful mid-water schooling fish with compatible water requirements
Bottom-dwelling peaceful catfish that occupies a different zone and poses no competition
Hardy, active fish that helps with algae control and shares similar water parameters
Fast-moving schooling fish that can hold its own and shares compatible conditions
Common Diseases
Ich (White Spot Disease)
Small white spots resembling grains of salt on the body and fins, flashing or rubbing against surfaces, lethargy
Raise water temperature gradually to 28-30°C, treat with aquarium salt or commercial ich medication containing malachite green or formalin; perform regular water changes
Fin Rot
Frayed, ragged, or disintegrating fin edges, sometimes with reddening or white margins at the affected areas
Improve water quality with frequent water changes, remove any aggressive tankmates, and treat with antibacterial medication such as kanamycin or commercially available fin rot treatments
Velvet (Oodinium)
Fine gold or rust-colored dust-like coating on the skin, rapid gill movement, clamped fins, flashing behavior
Dim tank lighting, treat with copper-based medication or acriflavine; raise temperature slightly and perform water changes
Dropsy
Swollen abdomen, raised or pinecone-like scales, lethargy, loss of appetite
Isolate affected fish immediately, treat with Epsom salt baths and broad-spectrum antibiotics such as kanamycin; improve overall water quality and nutrition to prevent recurrence
