I have a 5 inch odoe pike and a 6 inch dentex brycon they look similar. But would they school together if I got more brycon and more pike (2 more of each) I'm trying to get them to be more friendly because the brycon intimidates the odoe pike and the pike is always hiding.so my question is do similar looking fish school together. If they do I would like to get plenty more predator silver looking fish.
