(16) Temensis Peacock bass 7-8in

The temensis peacock bass (Cichla temensis) is the largest and one of the most stunning species of peacock bass, a group of predatory South American cichlids. Also known as the speckled peacock bass or three-barred peacock bass, this fish is highly sought after by experienced aquarists due to its size, vibrant colors, and intelligence.

• Size: Cichla temensis can reach up to 30 to 36 inches in captivity, with some wild specimens exceeding 3 feet.
• Color variations: This species has distinct color patterns depending on its breeding cycle:
  • Non-breeding: Known as "tucunaré paca," they have a mottled pattern of dark olive with light-colored speckles.
  • Breeding: Referred to as "tucunaré açu," they display three bold vertical black bars over a golden-olive body. Some males develop a pronounced nuchal hump on their forehead. 

• Tank size: An adult requires a minimum tank size of 300 to 500 gallons, with many aquarists opting for larger, custom-built tanks or indoor ponds.
• Water parameters: They thrive in warm, slightly acidic water.
  • Temperature: 75–82°F (24–28°C).
  • pH: 6.0–7.5.
• Filtration: These fish are messy eaters, so robust mechanical and biological filtration is critical for maintaining pristine water quality.
• Aquascaping: A fine gravel or sand substrate is ideal. The tank should provide a balance of open swimming space and cover from driftwood or large, secure rocks. A heavy, tight-fitting lid is essential, as peacock bass are known jumpers. 

• Predatory carnivore: Cichla temensis are voracious predators that feed primarily on live prey in the wild.
• Aquarium diet: A varied, high-protein diet is essential for their health and growth. Acceptable foods include:
  • High-quality carnivore pellets and cichlid sticks
  • Frozen foods like shrimp, krill, and fish fillets
  • Whole feeder fish (use with caution due to the risk of introducing disease) 

• Temperament: Temensis peacock bass are aggressive, territorial, and will eat any fish small enough to fit in their large mouths.
• Tank mates: Suitable companions must be large, robust, and able to hold their own.
  • Compatible: Large cichlids, arowanas, and certain large catfish can cohabitate in very large setups.
  • Incompatible: Small or delicate fish, as well as invertebrates like shrimp, will be seen as food. 

• Challenge: Breeding temensis peacock bass in captivity is challenging, requiring a very large aquarium and stable, optimal water conditions.
• Process: They are substrate spawners and become very territorial when protecting their nest. The parents guard the eggs and fry, and the fry eventually disperse after about two months
