Overview

The Red Tail Barracuda is an ominous looking fish with a long, slender, silver body with a bright red tail. The most distinguishing characteristic of this fish is the large sharp teeth that are easily seen. Often referred to as the Dog Characin, Freshwater Barracuda, Spotted Cachorro, or the Amazon Cachorro, this fish is a Characin related to both tetras and the piranha.

A 70 gallon or larger aquarium that is well established is ideal for this species. Provide the Red Tail Barracuda with driftwood in order to maintain a neutral to slightly acidic pH and soft water. There should be plenty of open swimming areas. A vicious predator, the Red Tail Barracuda should only be housed with other more aggressive predacious fish of similar size. Ideally, it is best to not place this species with territorial species of Cichlids.

The breeding habits of this species are unknown, and the Red Tail Barracuda has yet to be spawned in the home aquarium.

The Red Tail Barracuda is a carnivore and should be fed a variety of live foods such as small fish and crustaceans.

Approximate Purchase Size: 3" to 4"

My barracuda is housed with a Green Terror and a Red-bellied Pacu. The barracuda is the least aggressive of the fish despite it being the largest (6 inches). It will only eat live feeders. I have offered a variety of foods like pellets, bloodworms, and live worms (night crawlers). Its teeth make it an impressive fish and it is worth the added attention.

I have two Red Tail Barracudas, two Yellow Tail Barracudas, and a freshwater Moray Eel in my 120-gallon tank. All the Barracudas are a foot long or shorter, but they are usually calm until it's feeding time. Freshwater Barracudas are a miraculous fish. They are a must-have in a freshwater aquarium.

Awesome fish. Not aggressive towards fish that can't fit in it's mouth. Much more tolerant of softer water, so if you live in an area that has hard water try adding in something like Neutral Regulator by Seachem or a similar product.
