Answer 2

its a vicious type of fish that lives in both freshwater and saltwater... it usually eats feeder fish or basically whatever fish that can fit in its mouth. it can grow up to 6 or more inches long. i wouldnt recommend putting it in with non aggresive (or communitive it means the same thing), or semi aggresive fish, or any fish that is smaller or the same size as the barracuda... you would much rather put it in with another barracuda, another type of aggresive fish, or something bigger than the barracuda.

Well i hope this answers ur question :^D
