It has always been my understanding that most would recommend a 20 gallon tank for the first
goldfish, and 10 for each additional goldfish. Yet the goldfish profile on FishLore states a 10 for the first goldfish, and then another 10 for each additional. Also, perhaps this is just a personal preference but shouldn't the profile state somewhere that, although goldfish can adapt to a wide array of temperatures, they really thrive from about 64-72F? I know that most of us generally advise NOT to keep goldfish with other tropical fish, but IMO the profile suggests that this is actually advisable (suggests platies and possibly guppies as tankmates). Perhaps along with the info that goldfish can live in a wide array of temperatures, there can be some stipulation that they are most suited to the 64-72F range?
I realize that we probably are not allowed to edit the article. I would absolutely be willing to write another one aside from the fact that I've never kept goldfish and don't feel very qualified to write about them. But perhaps another member would like to volunteer to write it?
Thanks
