We’re going to a bigger city for the day soon, and I’m hoping to find some fish to finish stocking my 20g. The city is 2 hours away and we have an appointment to go to before coming home. Depending on what I find and when (we’re going to go to several places), the fish might end up being in the bag for about 5 hours (or less). How long can the fish be in the bags? Should I do anything like, open the bags, stir the water? Should I bring a completely separate container? I’ve only ever brought fish home from places close to me. I know fish are shipped in bags all the time, but I want to make the trip as least stressful as possible for them, making sure they have enough oxygen. Any tips?
