Okay so this weekend Im planning on buying me new little guy for my Birthday! And I am going back home and I thought since I like that Petsmart way better than the one near my school I wanted to buy him there. I have travelled with my previous betta before. I Normally just put him in his little cup and drive its only 3 hours... What can I do to relieve my new betta from stress during the car ride? I will probably get him Sunday. Should I leave him in the little cup overnight or should I do a water change in that little cup?
