I'm not sure you're disagreeing with me. I didn't say the fish benefit
overall from an elevated temperature, only that their immune response
improves. The situation is somewhat analogous to humans getting a fever:
our high body temperature isn't really "good" for our bodies overall, but it
sure gets the immune system cranked up to fight off pathogens.
IMHO, however, it doesn't matter much how or even whether increased
temperature fights "ich" in a plant tank, since many common plants suffer
more from the higher temperature than they would from "ich" medications.
jim - in Milwaukee, that never saw a 90 degree this July.
