Dorado Catfish (Brachyplatystoma rousseauxii)
Dorado Catfish (Brachyplatystoma rousseauxii)
The Dorado Catfish is a legendary South American river predator, known for its sleek, torpedo-shaped body, metallic sheen, and incredible speed. Native to the Amazon and Orinoco basins, this species is built for long-distance migration and powerful open-water hunting. Its streamlined profile and aggressive feeding behavior make it one of the most impressive large catfish available in the hobby. Due to its massive size and constant activity, the Dorado Catfish is strictly recommended for very large aquariums or indoor ponds.
Diet
Dorado Catfish are highly carnivorous, fast-moving predators:
- Fresh or frozen fish (silversides, smelt, tilapia)
- Shrimp, prawns, and other meaty foods
- High-protein sinking carnivore pellets (can be trained)
Frequent feeding is required for juveniles due to their rapid metabolism and growth rate.
Tank Requirements
- Minimum Tank Size: 300+ gallons (juveniles), pond or 1,000+ gallons for adults
- Water Type: Freshwater
- Temperature: 74–82°F
- pH: 6.0–7.5
- Setup: Open river-style setup with strong flow; minimal décor; heavy-duty filtration required
This species is an extremely active swimmer and needs long, unobstructed swimming space.
Size
- Current Sale Size: Typically 4–10 inches
Max Size
- Maximum Adult Size: 4–5 feet (48–60 inches)
Tank Mates
Tank mates must be large and robust due to the Dorado’s predatory nature:
- Compatible: Large, fast, and durable species such as arowanas, pacu, large catfish, and stingrays
- Use caution: Even large fish may be chased or eaten over time
- Avoid: Small or medium fish, slow-moving species
Only house with fish too large to be swallowed and capable of handling strong feeding competition.
Temperament
Highly active and predatory. Not overly aggressive in terms of territory, but extremely powerful and food-driven. Constant swimmer that dominates open water.
