i use to catch 1000's in a net to sell or trade.. runoff ponds duck ponds ponds on golf courses just about any pond around college dorms or apartments. funny thing tho never caught one with a hole in his head. if you think about it the problem in theory is lps , breeders, both with out licences, over breeding causing all kinds of genetic problems not only in these two. Breeders and show folks are using #10 colo renhancers that eventiually wear off kinda sad. In my aeria they are tatooing albino oscars. As a suggestion garlic reduces risk of internal pests. If you have ever dissected a gold fish you would never feed them to your friends. LPS are even selling pecockbass just to make a buck, you can catch 5/10/15 pounders in canals in florida all day long.
