Red Belly Piranha

Red Belly Piranha (Pygocentrus nattereri) is native to specific tropical and subtropical freshwater systems. Captive-bred specimens at most LFS come from generations of farmed stock and are generally hardier and more colorful than wild-caught equivalents.

Red Belly Piranha requires a minimum of 75 gallons for healthy adults. The minimum is based on 12 inches adult size and territorial range. Plan a tank sized for adult footprint, HOB or canister filter rated 4-6x volume, dechlorinated water, appropriate temperature heater, and stocking-appropriate hardscape.

Red Belly Piranha prefers freshwater parameters: temperature 74-80°F, pH 6.5-7.5, GH 4-12 dGH, KH 3-8 dKH, ammonia + nitrite 0 ppm, nitrate under 20 ppm. Use dechlorinator on every water change.

Red Belly Piranha is a carnivore. Provide frozen mysis, brine, finely chopped seafood, and quality carnivore pellets. Live food triggers feeding response in stressed arrivals. Browse our food guides for product recommendations.

Red Belly Piranha works in community tanks with peaceful species in similar size class. Avoid mixing aggressive with passive species.

Red Belly Piranha reaches 12 inches at adulthood with a captive lifespan of 10-20 years with proper care.

Red Belly Piranha can be bred in dedicated breeding tanks with appropriate setup and water-chemistry triggers. Research the species-specific breeding requirements before attempting.

Red Belly Piranha is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Red Belly Piranha for 4 weeks before adding to display.
