For what the crayfish cost, spend the extra $ and have one day shipping. It's not the temp, it's the amount of O2 in the bag. The bags, when they arrived here were about 1/2 full of water.
Remember, they're swimming/crawling in their own pee and poop for 2 days.......
A client had some shipped 2nd day, and it wasn't pretty.
The ones that were shipped next day came thru fine.
