Today, I went to my lfs and saw a silver arowana (around 7 inches).. but this one is kinda different.. the side and the pectoral/pelvic fins are white, only the top is kinda silverish and the dorsal / anal / caudual fins got a little dip of fading red.. Is this the normal look for silver arowana? Just curious... 
Will try to get pic later this evening
