Blue Dolphin Catfish (Cetopsis coecutiens)


An unsual catfish found throughout most of the Amazon basin, the Blue Dolphin or Torpedo Catfish is a specialized predator/parasite adapted for feeding on larger fish and dead animals in the wild. A powerful, active swimmer, this fish feeds by seeking out large fish and taking substantial bites with their highly specialized “cookie cutter” like mouths. They also feed on dead fish and mammals, burrowing under skin and hollowing out the body. In the aquarium, they do best in a large tank with plenty of open swimming space and moderate to strong current.
