Red Tail BarracudaSpotted Cachorro ~ Freshwater BarracudaFamily: Acestrorhynchidae Acestrorhynchus falcatusPhoto © Animal-World: Courtesy David BroughLatest Reader Comment - See More I've had my barracuda for about 2 weeks and in all this time I have never seen him eat? Another observation is he's not very active. Charles Not your typical Characin, the Red Tail Barracuda is a streamlined predator that is referred to as a Freshwater Barracuda!Red Tail Barracuda Contents The Red Tail Barracuda, also known as the Spotted Cachorro, has become a more common import in the last several years. It is one of a dozen or so species belonging to the genus Acestrorhynchus. It doesn't take much of an imagination to see why species of Acestrorhynchus are called Freshwater Barracudas. The slender body shape and a mouth full of sharp teeth says it all. Despite its size, appearance, and behavior however, this fish is not a true barracuda. It is a Characin just like the more familiar tetras, hatchetfish, and pencilfish. As long as you are willing to provide live fish as food, the Red Tail Barracuda makes a great aquarium pet. They do get pretty big and being from a river environment, they need a lot of swimming space and clean well oxygenated water. They are a very interesting active fish though a bit on the nervous side. They do best with company and can be kept in a small school or with other companion fish. They will usually do very well with other similarly sized tank mates.

Habitat: Distribution / Background
The Red Tail Barracuda, also known as . the Spotted Cachorro, was described by Bloch in 1794.

The Red Tail Barracuda are carnivorous piscivores. They only eat live foods, and they prefer fish! Because this is what they like to eat, a good practice is to setup a small tank to keep a steady supply of small, live feeders available. You can also offer them earthworms, river shrimps, and other good sized invertebrates.
This is a species that requires lots of space to thrive. Even though they don't get all that large, a minimum tank size of 50 gallons is necessary to keep them in good condition. They also require good filtration with some current. These are very active fish and will need a great deal of open area for swimming, but they are also a nervous fish that frightens easily. Providing a decor with some tall plants around the perimeter, possibly some floating plants as well, will help make them more secure and comfortable.
