Hello, everyone! In a few weeks, I'm going to have to transport my fish home from college for break! I was going to transport them in the cups I bought them in like I've done before, but because it's winter and I live in the midwest, and one can never be completely sure of if the heat is going to work consistently, in a vehicle, I was wondering if maybe I should buy two small thermoses to transport them in. Would this help regulate the the temperature at all? It's a fairly long drive (5-6 hours). I was thinking of putting them in fish bags and then putting them in the thermoses for the trip. Good/bad idea?
