Man I had a 5inch ornate that was super mean I tried to put a delhezi and a albino senegal with him and he would not allow it. I also bought a young 4 inch silver arrowana and my ornate killed it.
usually true but not always. i had my butti for a couple to 3 yrs and pretty much got along with all my fish until just recently he started acting like a ahole. my friend took him off my hands.
here is a video of my butti i had to get rid of which sucked. the op can see my fully grown jag also in the vid http://www.youtube.com/watch?v=ykeqW-yHLcQ
