You may want to look very close. Although they are not large he does appear to have a very small tuft at least on this side. and I am sure you know if he has the (Et) gene he is capable of producing tufted offspring. I wish I lived closer also as he seem's to be of very good type as well.
As to size, I myself am not sure. I have never seen any aruacanas except those I hatched out from shipped eggs, which were sold as purebred aruacana. So I,m not sure how big they are supposed to be. He is either a largish bantam or a smallish LF. Smaller than all my other LF, but bigger than my banties. I only had three to hatch all together (I never have luck with shipped eggs). None were tufted, the two roosters were tailess, and the hen was non tufted and had a tail. The feathers at his ears look to be the samr little feather patch all other roosters have.
