[GSAS-Member] Fish & temperature

[DELPHILABS@aol.com]

Hello all,
 
I am glad that I started this thread -- some good  observations.  
 
My own theory is that our fish in tanks are much more stressed  than in 
nature.  Try as we might, the environments we create are no  substitute for 
nature. 
 I think that our aquarium fish are much more  susceptible to disease than 
the same fish in nature.  Sudden temp changes  could be the straw that breaks 
the camels back.
 
Also, using Clay's fine analogy, the kid that lives in the  Pacific Northwest 
and is in and out of doors all day long is much more robust  and acclimated 
to endure a wide range of temp change.  A kid that spent his  whole life in 
Hawaii puts on a coat when it gets below 70 degrees.  Maybe  if we cycled the 
temperatures in our aquariums the fish would become more  tolerant?
 
This is fun, how about a couple more? Has anyone had a fish  that hangs 
around a hot heater like you would expect of a cold blooded reptile?  I've 
never 
seen that in my tanks.
 
Also, my observation diving all over the world, is that most  species are 
always in pairs (or schools) in nature.  You especially see  this in 
Butterfly's 
and Angels. I used to keep a lot of single fish when I did  saltwater aquaria 
years ago.  If I ever get back into it, I will ALWAYS try  to get pairs.  I 
wonder if any of my fish ever died from "loneliness"   :-(
