This is really non-breeder specific but I thought the breeders here would be most knowledgeable. When you are jarring, what, up to 100+ bettas, do you do daily or every other day water changes (if you don't use a filter system with your jars)? And with those daily or so changes, does it stress the fish? I just wonder because I see how so many here say a filtered tank is best, but not all breeders use filtration for their fish. So I'm curious on your water change routine, the details of it.
