I got this fish today and was told it is a Sharknose Goby but most of the info I have been able to find say they max out in size at 1.5-2 inchs. The guy I got in this picture is a hair over 3 inches and seems to have a lot of yellow in his coloration, not just around the head as seen in most pics and description. Anyone want to confirm that this is a Sharknose, or possibly something else? Given the size disparity and the color variation I am wondering if the labeling was accurate.
