This toothy grin belongs to the Red Tail Barracuda, a fresh water fish that can be found in the rivers of Guyana, Suriname, French Guiana, as well as the Amazon and Orinoco River systems where they tend to collect in schools of other Barracuda. Growing up to 11 inches and living up to 10 years, these quick predators eat other live fish/invertebrates. Some specimens can be trained to take frozen food, however it is not always a guarantee they will accept it. All pictures shown are for illustration purposes only. Actual products may vary due to natural variation with livestock.
