This is just a starting point.
Small Juvenile Peacock Bass (1–6 inches)
Small Juvenile Peacock Bass (1–6 inches)
- Key Considerations:
Juveniles are vulnerable, aggressive feeders, but still small enough to be eaten by larger fish. You want similarly sized, peaceful to moderately aggressive fish that won’t outcompete or injure them.
- Best Tank Mates:
- Silver Dollars (Metynnis spp.) – Fast, peaceful, and big enough not to be eaten
- Large Tetras (like Congo Tetras) – Active and tough
- Young Severums (Heros spp.) – Calm and hardy
- Bichirs (small species like Senegal Bichir) – Bottom dwellers, not a threat
- Medium-size Plecos (like Bristlenose) – Cleanup crew, but pick armored types
- Flagtail Prochilodus – Fast, tough, algae grazers
- Geophagus Species (like Red Head Tapajos) – Sand sifters, peaceful
- Tank Mate Size Rule:
Choose fish that are at least half the size of the bass to avoid being eaten.
- Key Considerations:
Large peacock bass are extremely predatory and will eat anything they can fit in their mouth. You need big, tough, and fast tank mates.
- Best Tank Mates:
- Large Catfish (Redtail Catfish, Tiger Shovelnose, Pictus Catfish) – But watch the size
- Arowanas (Silver, Black) – Surface swimmers, need large tanks
- Large Oscars – Aggressive enough to defend themselves
- Large Clown Knifefish – Shy but can grow huge
- Datnoids (Indo Datnoid, NGT) – Heavy-bodied, slow-moving but not easy prey
- Large Silver Dollars (over 6 inches) – Schooling for safety
- Large Bichirs (Ornate, Endlicheri) – Stay at the bottom and are tough
- Giant Gouramis – Tough and peaceful if large enough
- Tank Mate Size Rule:
All tank mates must be at least ⅔ or larger the size of the peacock bass.
- Tank Size: Bigger is always better. 250–500+ gallons ideal for adults with tank mates.
- Feeding: Feed the bass well to reduce aggression toward tank mates.
- Hiding Spots: Driftwood, caves, and plants help weaker fish escape the bass’s attention.
- Compatibility: No tiny fish (they’ll be snacks), no overly aggressive fish (can stress or injure the bass).
