I was wondering if anyone has had any experiece keeping freshwater barracudas and what they are like, opinions on tankmates for them would be helpful as well
Which ones? redtails, hujetas, cachorros, and even needlefish are all sold under that name. They all tend to be great predators towards smaller fish, hard to get off live food, a bit fragile with bullying full bodied fish, not aggresive towards fish that are to big to eat, and a bit skittish.
