I have a 75 gallon tank with two biowheel 330 filters on it and 8 goldfish in it, 5 of which are large. Somebody told me that the tank was overstocked. Actually, they told me the tank was overstocked when I had either 5 or 6 in it. They seem happy and actually were happier when I added the babies. I must say that this person is one of the people who gave me lousy advice in other situations. I also was told that they can live to be 30 and on another occasion 100 years old. I just wanted to check with the experts. Anyone?
