For me, it would be yest to both. Moving a fish from the main tank to QT
is stressful enough without the added burden of acclimation to new water. Plus, it's FAST.
I always have 15-20 gallons ready to go for changes. I have small rubbermaid garbage can in the corner of my "fish room" with a heater and flowhead w/air bubbles.
It's working so far!!!!
