Can't believe this thread is still going. Guess I'll make some updates.
1) Found out he is a jumper. I was out of town for 9 days, on the 8th day, I got a call from my wife saying the arowana jumped. Behind the aquarium. But she got him. Luckily, it was her day off, and he decided to jump while she at home. He flipped and flopped his way to one of the front doors on the stand where she netted him back in. She thinks I would have killed her if one of my big fish died on her watch.
2) Still super red. Eating Tetra JumboKrill mainly.
Gets ghost shrimp occasionally and a feeder on rare occasions.
3) Just an awesome fish to watch.
