Having read through the whole thing again, I'd like to go back to the temp thing again...
Will the fish not be bothered by the temp slowing dropping in the bucket while they are acclimating? I realise you can slowly raise the temp again after, but will they have issues with the lower temp for a few hours? Obviously fish like corys which like lower temps wouldn't have so much of an issue but those fish that like warmer temps - would they become stressed by a drop in temp, even though it's very slow?
