I wanted to get an Oscar but their tank requirements are way to big. Oscars look really cool to me because my friend has two and they eat prettymuch anything he throws in their and they are always jumping at the lid of the tank if they think you have food, their badass. Are their any extremely aggressive fish that act like these oscars that could go in a 10-20gallon tank??? I want a fish that will try and bite me. haha
