🐟 Whale Catfish – (Cetopsis candiru) – Powerful South American Predatory Catfish
The Whale Catfish (Cetopsis candiru) is a rare and formidable predatory catfish from the fast-flowing rivers of South America, particularly within the Amazon and Orinoco basins. Named for its large, rounded body and massive head reminiscent of a whale, this species is a muscular, deep-bodied fish built for strength and speed.
In the wild, Whale Catfish are opportunistic feeders and scavengers, consuming fish, invertebrates, and even carrion. They are known for their voracious appetite and strong swimming ability, which allows them to thrive in fast currents. In aquariums, they require spacious tanks, powerful filtration, and should be kept only with equally robust, non-prey tankmates.
