You'll probably want to quarantine those fish (which I think you did?).
I've found that redfin shiners collected-in-any temp above 70 is a pretty
perilous proposition, especially when they've been subjected to heat and
oxygen stress. They're parasite factories in those situations and I've seen
them take down whole systems twice now from introduction. The temps in
those pools are swinging like crazy and up into the upper limits of what
those fish can handle, and to make it more difficult for them, the dissolved
oxygen will crash-in-night after plants and algaes stop photosynthesizing
and only respire.
It may seem like a humane thing to "rescue" them from those pools, but
remember... That's just part of the nature of things, they're probably
"dead" already, and killing fish already captive isn't really doing any good
in the world :) If you get this batch through, I'd keep them where they
are and move any new rescues into their own other tank.
Might also be an interesting science project to do with Shawn for interest
sake or if he's got a science fair coming up. You could observe these pools
during this time period and look-in-what members of the community are dying
off, who survives, what the extremes are, etc. Could also have aquaria set
up (so they're cycled and whatnot) and bring stuff home and look-in-who's
actually just the "living dead" or where transportation stress puts them
over the top.
