🐟 How to Care for Peacock Bass (Cichla Species)
Peacock Bass, particularly species like the Kelberi, Orinoco, and Mono, are some of the most stunning and rewarding freshwater fish to keep — but they’re not for the faint of heart. These powerful predators demand space, a carnivorous diet, and knowledgeable care. If you’re ready to dive into the world of Peacock Bass, here’s everything you need to know to keep them thriving in your aquarium.
📏 Tank Size & Setup
Minimum tank size: 125 gallons for juveniles; 210+ gallons for adults.
These fish grow large — often reaching 18" to 30" depending on the species. Make sure to plan for adult size!
Ideal tank features:
-
Plenty of swimming space with open water
-
Strong filtration (canister filters, sumps, or both)
-
Secure lids – they’re strong jumpers!
-
Driftwood, rocks, or minimal décor – avoid sharp edges
🌡️ Water Parameters
-
Temperature: 76–82°F (24–28°C)
-
pH: 6.5–7.5
-
Hardness: Soft to moderately hard
-
Ammonia/Nitrite: Always 0
-
Nitrates: <40 ppm
Weekly water changes (25–50%) are key to maintaining stable conditions.
🐠 Diet
Peacock Bass are carnivores. In the wild, they feed on smaller fish and crustaceans. In captivity, aim for a protein-rich, varied diet:
-
Frozen shrimp, tilapia, or silversides
-
Live feeders (quarantine first!)
-
High-quality carnivore pellets (e.g., Hikari, NLS)
-
Occasional krill, earthworms, or smelt
Pro tip: Train young bass early to accept frozen or pellet food for easier long-term care.
👥 Tank Mates
Peacock Bass are predators – anything that fits in their mouth is food. Good tank mates include:
-
Other large Cichla species
-
Arowana
-
Large catfish (e.g., RTC, Lima shovelnose)
-
Silver Dollars (if big enough)
-
Datnoids, Oscars (size permitting)
Avoid small fish, slow swimmers, or delicate species.
⚠️ Common Issues
-
Aggression: May show dominance, especially in smaller tanks
-
Stress from poor water quality or undersized tanks
-
Refusal to eat prepared food – train slowly using scent triggers
-
Hole-in-the-head disease – usually from poor diet or water quality
Routine maintenance and a good diet prevent most problems.
