Peacock Bass Orinocensis

The Peacock Bass Orinocensis, scientifically known as Cichla orinocensis, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 60 cm and have a fusiform body shape with a fast growth rate. Classified as aggressive, this species primarily occupies the mid-level and surface zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Peacock Bass Orinocensis requires a freshwater only aquarium with a minimum volume of 750 litres and a tank length of at least 200 cm. Water temperature should be maintained between 26°C and 31°C, with a pH range of 5.5–7.5 and a general hardness of 2–15 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Peacock Bass Orinocensis is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard / Adult and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Peacock Bass Orinocensis, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and surface zones, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline and open swimming space in the centre of the tank for free movement. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper and expect substrate disturbance, so lightweight décor should be secured.

Classified as aggressive, the Peacock Bass Orinocensis is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and surface zones can help reduce competition and territorial overlap.
