Lets see here. They look frickin AMAZING, never hide, fufill the upper level of the tank that is often empty, prehistoric factor, float through the water like dragons, provide good luck. I believe they resemble dragons (note how they swim... like a dragon flying through the air). They're colors (gold & red) are both very lucky especially with those involved in Feng Shui. There's a story that the first person to keep an an arowana in a tank struck upon a fortune
Asian arowana though, are much nicer than their american counterparts, i can see if you dislike those a bit. Asian aro have soo many different colors and kinds... amazingly beautiful!
