Ive had quite a few africans in the last 10years, I currently have 5 or 6, of those, my red zebra (think he is a red zebra although he is more white than red) is easily the nastiest and sturdiest one of the bunch. By far. Had an auratus years ago, remember him being pretty bad, I picked up another one tonight, I was just wondering how their agression level stacks up to the red zebras? Thanx!
