No, I never lost any fish. I can see your point though. I am no expert on temperature swings and fish health or acclimitazation, but my guess is that the fish are more likely to be negatively impacted by constant fluctuations in water temperature frequently over several days or hours. They could probably adapt to the odd temperature swing if it was not too drastic and with the drip method, because the water is only flowing into the bucket at a rate of 1-2 drops per second, I would think the any changes in temperature(up or down) would be too slow too have a real impact on the fish(unless you do this in a really cold room) and by the time you put the fish in the water, he would be in the water with the temperature that he has already adapted do. With the float bag method you are dumping larger quantities of water in the bag over a shorter period of time, so I would think that this would cause a more dramatic fluctuation in temperature in the fish bag water.
You do raise a really interesting point though and that is one of the reasons that I am fearful of trying those automatic water change hoses with the siphon that hook up to your faucet. I imagine the temperature change introduced by the new water would probably cause a greater fluctuation in temperature. How do people who use such devices deal with this? Are your heaters sufficient to quickly stablize water temperature after such a change or do you try to match the temperature of the faucet water to your tank water before letting the water flow into the tank. I let buckets of water sit at room temperature and use this water for my water changes.
