Cetopsis Orinoco, commonly known as the Orinoco Cetopsis or Orinoco Catfish, is a species of freshwater catfish belonging to the family Cetopsidae. It is native to the Orinoco River basin in South America, specifically found in Venezuela and Colombia. The Orinoco Cetopsis is a fascinating and unique fish species, known for its elongated body, nocturnal behavior, and specialized adaptations for navigating dark and murky waters.
- Size: The Orinoco Cetopsis can grow up to 8 to 12 inches (20 to 30 centimeters) in length, depending on its age and living conditions.
- Body Shape: They have an elongated and cylindrical body shape with a flattened head and a small mouth, equipped with sharp teeth.
- Coloration: Their coloration is generally dark, ranging from brown to black, which helps them blend into their dark and murky river habitats.
- Temperature: Maintain a tropical water temperature between 72°F and 80°F (22°C to 27°C) to ensure the well-being of Orinoco Cetopsis.
- pH Level: Aim for a slightly acidic to neutral pH level between 6.5 and 7.5 to replicate their natural habitat.
- Water Hardness: Provide moderately soft to moderately hard water with a hardness level between 2 and 10 dGH.
- Tank Size: Due to their adult size, the Orinoco Cetopsis requires a spacious aquarium of at least 75 gallons (284 liters) to accommodate their growth and swimming needs.
- Substrate: Use a soft and fine-grained substrate to mimic their natural river habitat and protect their delicate barbels.
- Hiding Spots: Provide plenty of hiding spots using driftwood, rocks, and caves to make them feel secure.
- Carnivorous Diet: Orinoco Cetopsis are carnivores and prefer meaty foods.
- Sinking Pellets and Live Foods: Offer high-quality sinking pellets, wafers, and occasional live or frozen foods such as bloodworms, brine shrimp, and small insects.
- Nocturnal: Orinoco Cetopsis is primarily active during the night, so providing dim lighting during the day is beneficial.
- Bottom Dweller: They are bottom-dwelling fish and spend much of their time searching for food in the substrate.
- Due to their nocturnal and somewhat secretive nature, they may not be the most active fish during the day.
- Maintain excellent water quality through regular water changes and efficient filtration.
