Thanks everyone. :) I was able to convince mom that we should eat, pack, and then leave. So little fish was safe in his tank, up until we left. When we went to return the furniture cart I took him in his little cup with me and mom was like "Why are you bringing the fish with us, just leave him in the car!" And I said no and carried him anyway. lol.
On the ride here (45 min or so) mom had the AC on in the car so I had my legs sitting in a pretzel style, a towel layered like 3 times, and he was sitting warm and cozy in the hole made by my legs, in the towel, nice and warm for the ride. :D I'm currently acclimating him to new water right now. Put some AQ salt in his tank to help with his stress, poor thing. I'll keep you all updated.
