More personality than my dog

I am not exaggerating when I say my Oscar has more personality than my dog. He splashes at me when he wants food, rearranges the decorations in his tank whenever he feels like a change, and pouts visibly when I go on holiday. He is eight years old, the size of a dinner plate, and the single most entertaining animal I have ever owned. If you have a big tank and good filtration, get an Oscar.
