Shape of mouth also.Those are Brycon. Big eye, taller and lots of red fins.
Nothing jumps out, but slight diffences in head and fin proportions to me. Body shape on one does seem a bit more streamlined. Hill plate shape is slightly different. Main difference to me is in the fins but it's so slight I'd say it could be due to genetics.Who can dodge a wrench!?!?!

One of these fish is not like the other....... Anyone see anything that jumps out as being different?
