Have any of you guys tried common goldfish? I bought a dozen from a bait store yesterday and put them in a couple of very small stock watering tanks. I want to see what they do to the plants. I remember that my grandfather put them in a 2,000 gallon galvanized water tank that the cows drank out of. I assume that it was to keep down the algae.
I know they are going to turn into carp and herons will get some of them but, I'm curious. I just don't see much difference in koi and goldfish other than price.
