(102) Monoculus Peacock Bass 3-5''

The Monoculus Peacock Bass (Cichla monoculus) is a large, predatory freshwater fish from the Amazon Basin. Prized for its striking iridescent coloration and "mono eye spot" on its tail, it is a magnificent but demanding species that requires significant space and specialized care. It is only recommended for experienced aquarists who can provide a "monster fish" setup.

• Tank size: A single adult Monoculus Peacock Bass can grow to 30 inches or more and requires a minimum of a 200-gallon aquarium. For multiple specimens, a tank of 300 gallons or larger is necessary. The tank should be long and wide to provide ample swimming space.
• Filtration: A powerful and robust filtration system, such as a sump or multiple canister filters, is essential to manage the heavy bioload produced by this large, messy eater.
• Water parameters:
  • Temperature: Maintain a stable tropical temperature of 76–86°F (24–30°C).
  • pH: A slightly acidic to neutral pH range of 6.5–7.5 is ideal.
  • Water changes: Regular, large water changes are needed to keep nitrates low and ensure pristine water quality.
• Decorations: Provide some hiding places using large, secure pieces of driftwood and rocks, but leave plenty of open swimming space. Peacock Bass prefer a sandy or fine gravel substrate to prevent injury to their fins.
• Secure lid: A heavy-duty, tight-fitting lid is mandatory, as peacock bass are powerful jumpers. 

• Carnivorous diet: As a piscivore (fish-eater), the

   requires a high-protein, meaty diet.
• Food types: While often raised on live feeder fish, they can and should be weaned onto a balanced diet of high-quality alternatives, such as:
  • Sinking pellets designed for large carnivores
  • Frozen foods like shrimp, krill, and whole fish
  • Earthworms and other insects
• Feeding schedule: Feed juveniles daily and reduce the frequency for adults to a few times per week.
• Avoid: Do not feed live feeder fish from pet stores, as they can transmit diseases. 

• Aggressive and predatory: Monoculus Peacock Bass are highly aggressive and territorial and will eat any fish small enough to fit in their mouths.
• Social dynamics: They can be kept in a species-only tank or with other large, robust, and aggressive fish in a suitably large aquarium.
• Compatible companions:
  • Other large cichlids (e.g., Oscars, Jaguar Cichlids)
  • Large armored catfish (e.g., Redtail Catfish, Plecos)
  • Arowanas or large Silver Dollars
• Incompatible companions: Any small or slow-moving fish will be viewed as prey.
