Blue whale catfish Care Guide

The Blue Whale Catfish (Cetopsis coecutiens) is a fascinating aquatic entity, known for its social nature and unique behaviors. While they are rare, they are moderately affordable and require some specific care guidelines to thrive in captivity.

Care Process

The Blue Whale Catfish is moderately easy to care for, with a hardiness level rated as resilient. They prefer a water pH ranging from 6.5 to 7.5 and thrive in temperatures between 22°C and 26°C. These catfish are social creatures and can be housed in small schools of at least three individuals. A spacious aquarium, providing at least 150 liters of water per fish, is essential for their comfort and well-being.

Feeding

Blue Whale Catfish are omnivorous, requiring a varied diet to meet their nutritional needs. Suitable food options include flakes, pellets, bloodworms, brine shrimp, tubifex worms, frozen shrimp, vegetable matter, algae wafers, color-enhancing food, daphnia, micro worms, feeder fish, freeze-dried foods, and stick-on tablets. Regularly varying their diet helps ensure they receive all necessary nutrients and remain healthy.

Tank Setup

Given that Blue Whale Catfish are surface dwellers, mid-tank dwellers, and bottom dwellers, it's important to provide a diverse tank habitat. The aquarium should have a combination of open swimming areas and hiding spots, such as caves or dense plant areas, to mimic their natural environment. Mildly territorial, they should be monitored to ensure they are not overly stressed or aggressive with tank mates.

Behavioral Aspects

These catfish are known to have a mixed behavioral disposition — they can be social and playful at times but may also exhibit shy or aggressive tendencies. During breeding, they show no significant change in behavior, but it should be noted that successful breeding in captivity is quite rare and challenging.

Maintenance

The Blue Whale Catfish requires moderate maintenance. Regular tank cleanings and water quality checks are necessary to maintain optimal conditions. A filtration system that keeps the water clean and oxygenated is vital to their health. Consistent monitoring and adjustments to their environment will help these unique creatures thrive in captivity.
