Do you think fish get sick/stressed everytime there's a rain storm?

First, a rainstorm will most likely never replace 25% of a lake, probably not even 2%.. Second a 10 degree change in water temps is a big difference. I learned here, and reading that I should not chance it... Overcautious? maybe..

It is good to hear your fish have not been affected by such varying water change temps.. :)

No, a rainstorm won't change 25% of a lake. But it will change that much in a stream...And many fish available live in a stream at some point in time.

These changes kick off spawning behavior in many species.

I pour. I ensure the water is about the same temperature, but I don't obsess about it. I agree that large temperature changes can be a stressor, ......
I cannot find any evidence anywhere that ick can lie dormant for more than a few days.
It is good to let others know to keep the water 'about' the same temps. That's the point I'm trying to make. A temp gage helps out with this....

Ich can be dormant in gravel, or the fish. A weakened fish is an easy host.

Of course this is just what I have come to understand.. And, not by any means 'expert advice'. I'm always learning. :)

Rainstorms do not 'replace' or add 25% to a lake...
I'm just cautious about the temps. From most of what I have read and heard here about it, it's a good thing to keep the temps very close to the same.
