So we won a bunch of goldfish at our kids school carnival 3-4 years ago. Well we still have 1 left. We had to move him from a 20 gallon tank, to a 75 gallon tank. Because he is huge! His body shape is like a normal goldfish but much, much bigger! And his tail is just as big as his body but like a full, huge fancy tail. I can't find any pics on the net of any other goldfish that look like him/her. Just want to know what kind of goldfish him/ her is? He just keeps growing too! And has survived all the water problems we have had over the years.
