I Love my Goldfish!!! I was never very interested in them before, but almost 5 yeas ago We got our first one for our son, who was 1 as his first pet. I have been hooked ever since. I have 8 now most are 4-5 yrs old the youngest being one. We have watched them grow from tiny 1/2 inch long fish to now almost 6 inches long, living very happily in a 75 gallon tank! They are very entertain9ing and I can sit and watch them for hours. They are also very sweet, thye will let me stroke them and pet them(ha ha ha I know, I am weird!) I have never been all that interested in Bettas, they are pretty, but I just love my goldfish!
