Blue Turushuki Catfish
AquariumFish offers the unusual turushuki catfish, also called the blue sawtooth cat, or the ripsaw catfish for the serrated edges on its lateral lines. These remarkable fish, with their odd sawtooth edges, come in shades of blue and black. Though slow growers, these catfish should be kept with fish their own size and will grow very large over time.

The blue turushuki catfish is a striking addition to my aquarium. Its unique sawtooth pattern stands out and it’s very peaceful. I’ve had it for six months and it’s thriving in a large tank with other non-aggressive species.

Beautiful fish with a very distinctive appearance. It’s calm and doesn’t bother other tank mates. I’m impressed by how well it adapts to the water conditions in my 120-gallon setup.

First time keeping a large catfish and this one exceeded my expectations. The blue and black coloration is vivid, and it’s very active without being aggressive. Great for a spacious aquarium.
