Wild Caught Colombian Temensis Peacock Bass (8-9”)

Scientific Name: Cichla temensis

Maximum Size and Lifespan:
The Temensis Peacock Bass is the largest member of the peacock bass group, capable of reaching up to 36–40 inches (90–100 cm) in length and weighing over 20 lbs.

In captivity, they more commonly reach 24–30 inches (60–75 cm). Lifespan averages 10–15 years with proper care, though in the wild they may live slightly longer.

Recommended Aquarium Size, Water Changes, and Care:
Due to their enormous size and activity level, a very large aquarium or indoor pond is required. A single adult should have no less than 300 gallons , with 500+ gallons  being strongly advised for long-term housing or groups/community setups. Juveniles can be raised in 75-180 gallons for better observation.

They require powerful filtration, strong water movement, and high oxygen levels. Weekly water changes of 30–50% are necessary to maintain pristine water quality, as these fish produce heavy bioload. A tight-fitting lid is essential since they are powerful jumpers.

Tankmates:
Tankmates must be chosen carefully due to the Temensis’s predatory nature. Suitable companions include other very large, fast-moving fish such as large catfish and plecos, Arowana, Stingrays, Datnoids, etc. 

Diet:
Wild Temensis Peacock Bass are piscivores, feeding almost exclusively on smaller fish. In captivity, they should be given a varied diet frozen shrimp, sinking carnivore/massivore pellets, and floating hikari food/carnisticks.

Natural Environment:

In the wild, Temensis Peacock Bass are native to the Rio Negro basin in Colombia, Venezuela, and Brazil. They thrive in blackwater river systems characterized by acidic, soft water, submerged root tangles, and sandy substrates. Seasonal flooding and receding waters shape their life cycle, with peak feeding and breeding occurring during low-water seasons when prey fish are concentrated. 

Breeding:
Breeding Cichla temensis in captivity is extremely rare due to their size and environmental requirements. In nature, pairs form monogamous bonds, aggressively defending territories and spawning sites. Eggs are laid on flat surfaces such as submerged rocks or roots, with both parents guarding the nest and fry. In aquaria, successful breeding is seldom documented because of space limitations and difficulty replicating natural seasonal cues.
