If you put convicts in a tank with an already established school of blackskirt tetras or something with an equal temperament, what do you think would happen? Are convicts really as aggressive as people say to all fish or are they just aggressive because they're always placed with aggressive fish twice their size? Does anyone have any experience with this? I don't need a bunch of kids telling me it is awful if they haven't tried it before. I know it's probably not ideal, I'm just wondering if it might work.
