The shape o the head is not odd. Just that this fella ate too much goldfish pellet which I throw into the tank for the clown loaches. A very good eater. Took it 3 days before it gave in and accept pellet.
With great photo skill, expensive camera , good touch up editing & lots of color enhance pellet is just another common captive bred silver arowana hope everyone dont get too excited.
Anyway great looking young silver arowana.
