As a kid I had 2 goldfish in a pretty large fish bowl. When I got them I was told to change the water every 2-3 days and to fill gallon jugs of water the night before so it would be truly room temperature when I changed the water. This bowl was very heavy, so you can imagine how much work this was. I did not really keep up with how often they said to change the water though. I think I did it maybe twice a week, but usually about once a week, or maybe every 5 days.
In talking to a friend who also had fish she said this was totally incorrect instructions and that I was actually putting the fish in shock every time I changed the water because I changed all of it as I thought I was supposed to do.
I've never had fish since because it was just too much work for so little reward. What is the real proper care for fish kept in a bowl?
