Yes, but it's strange that the Red-Eyes gasp even during pearling, which I do
get by mid-afternoon (helped along by semi-diffused sunlight). And that none of
the other fish gasp, night or day.

Too bad I can't afford some sort of cooling system....

That's what I thought also. It seems strange that the Red-Eyes would be a limit
case here. Perhaps I'll try bubbling air in at night and see if that helps.

Thanks very much -- I appreciate your advice, Jerry!

all the best,
