Buying my first oscar. I had already started a peaceful community tank with tiger barbs, pictus cats, cory's, all kinds of stuff and a buddy of mine says, hey why don't you get a oscar? They have great personality. I didn't know a thing about them at the time and didn't do my homework. I sure picked the right one alright, I bought a tiger oscar. The moment I put him in the tank, he swam right after the school of tiger barbs. In less than a week he slaughtered all of my fish. I don't know why but I kept him but he became my favorite fish. Now I don't even mess with peaceful fish anymore. Too skiddish and boring.
I named him Kurgan after the bad guy in the Highlander movie. When he was small he would only eat the heads off of the fish. He passed away a couple of days ago. I had him for 6 years. Don't ever keep a pair of convicts in the same tank with your prized fish. Mean little bastards.
