For the past few years that I've owned goldfish, I've taken out my fish when I've done water changes. After watching Sakura/Solid Gold's water change vid, I've stopped taking them out. I've been doing this for the past couple months now and it's much more convenient for me. As long as I match the water temp from the faucet with the water in the tank, the fish still are fine. Anyone here have specific reasons why they take their fish out during water changes or vice versa? Id be interested in reading your comments!
