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.

Common Diseases

Ich (White Spot Disease)

Symptoms

Small white spots resembling grains of salt on the body and fins, flashing or rubbing against surfaces, lethargy

Treatment

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

Symptoms

Frayed, ragged, or disintegrating fin edges, sometimes with reddening or white margins at the affected areas

Treatment

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)

Symptoms

Fine gold or rust-colored dust-like coating on the skin, rapid gill movement, clamped fins, flashing behavior

Treatment

Dim tank lighting, treat with copper-based medication or acriflavine; raise temperature slightly and perform water changes

Dropsy

Symptoms

Swollen abdomen, raised or pinecone-like scales, lethargy, loss of appetite

Treatment

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
