So I was offered a 100 gallon tank (assumingly for free or dirt cheap) and plan to set up the tank rather soon. This is more or less an opinion based question, but what South Americans do you all recommend? I love red terrors, JD, GT, Oscars, whatever. Feel free to post your favorite South American fish or options that I can keep together (I hear red terrors are super aggressive). After I get some majority suggestions I'll probably post a pole to see which fish win out
