Don't know any good sites in Houston.  Let me know next time you're in
Ohio!

I also have pondered the question of how to keep water temperatures cool.
I have found, though, that it's not strictly necessary.  I was able to
spawn the rainbow darter this year by keeping a tank in the basement and
controlling day length.  The temperature probably did not fall below
about
65 F, and the fish probably spawned at about 70 F.  Aside from spawning,
I
am currently keeping darters and sculpins at temperatures between 70 and
80
F.  If you think about it, many of the streams that these fishes inhabit
reach quite warm temperatues in the summertime.  Using reasonable
aeration
in the tank should keep them fine (power head or good air pump).  The
main
danger is when taking wild fish from cool waters and warming them up too
quickly after capture.  Oxygen levels will drop and fish metabolism will
increase, often with fatal results.  Use a cooler to transport the fish
and
let them come up to room temp by sitting in the cooler with aeration
until
it room temp is reached naturally.

I do have a set of plans for a temperature controller for a refrigerator
which was intended for home brewing.  I haven't done anything with it
though.  Of course, you could invest in a chiller designed for a cold
water
reef tank- a little expensive though.  I can suggest a vendor if you
like.

Hope this helps.
