Thanks so much everyone. It's interesting that there is such a consensus on the species being an IJ, on the other forum I asked on everyone seems to think he's a coastal. I am on fact in the US and I do think that the lighting is what makes him look so yellow in those last two shots. The first photo is truest to his actual coloration. Can anyone clarify for me what indicators you are using to guess the variety? He is probably about 3.5 ft long and not quite 200 grams if I remember correctly. So that would be a normal size at two years old then?
