Blacktip Silver Shark Catfish

Catfish belong to the Ostariophysi, a group defined by a chain of tiny bones called the Weberian apparatus that physically links the swim bladder to the inner ear — essentially wiring a built-in subwoofer to their hearing, letting them pick up pressure changes and sounds most fish miss. This species puts that sensitivity to use as a fast, schooling open-water swimmer, covering serious distance and reacting to disturbances well before slower tankmates even notice.

Care level: Moderate · Temperament: Peaceful, shoaling · Max size: ~14" · Min tank: 75+ gal · Diet: Omnivore, flake/pellet + frozen
