RE: [GSAS-Member] Fish & temperature?

["Susan Welenofsky" <welenofsky@comcast.net>]

I've wondered about that too, Keith. I know that fish will swim up or down
in water, and that the temperature will change accordingly. When I add fresh
water, I usually just try to get it near the tank temp, and let it pour on
in through a python hose. Once I got the water temp really cold on accident,
and the fish became very slow and started drifting around like they were
dead. I mixed some warm water in and stirred, and eventually, they came back
to life.

Subject: [GSAS-Member] Fish & temperature?

When I am scuba diving with fish, I am always shocked at temperature and  
salinity changes as I am swimming around.  In some places the water
shimmers 
like oily water because fresh water is mixing with salt.  In some  places I
enter 
very cold thermoclines and in others the water feels like  bathwater.  The 
fish are swimming right alongside me.
 
How is it that we are so cautious about temperature changes in the aquarium

when they are the norm in nature?  I can see the concern over long term  
temperature levels, but during water changes etc, I wonder if it really much
of  an 
issue.  
 
I'd appreciate the list's thoughts.
Thanks!
Keith
