So i just started a 55 gallon today i have starter fish in there right now looking for suggetions on some Predatory fish that can live in a 55 Gallon. I am wondering if i could do freshwater barracudas. In there if anyone could let me know or give me some good ideas on fish that i can keep in there. I have done pirahanas and my dad has 2 red wolf fish so kinda looking for something different from those
