Okay so I am new and I wasn't sure where to post this, but anyways, I was wondering what I should put in a 75 gallon aquarium? I would prefer a carnivorous fish, but it doesn't really matter. I just want fish that stay in a school.
Either one or two nasty meat eaters or schooling fish.
Put the two together and all you will have are the carnivores. So you need to figure out what ya want.
Exodons would work they are schoolers and are meat eaters or smaller piranha but I believe the schooling species would require a larger tank eventually
