I always loved the peacock bass I had, but I have to say when it comes to personality I am a big fan of oscars. As common as they are they are still very fun to own. It's like having a trouble making puppy tearing around the tank. Mine is always up to something, and occasionally has a tendency to surprise me and sneak up to soak me during feedings. Jerk. Always gets in my mouth. I feel like it's intentional, like it's a practical joke. Either way he's a pig, and I always enjoy his antics.
