I can upgrade to a 55g cus I think most carnivorous fish get big aggressiveness is a plus this tank will be like a snke cage in a way with a large ornament for prey to hide so any suggestions would be nice.
snke* SNAKE
if you know for a fact you can upgrade, you can buy an oscar. they get to be at least a foot long and destroys the food you give it. same with a jack dempsey or a green terror. jack dempsey's are definately the most eye appealing.
