I have a betta in a one-gallon tank, but I am house-sitting for some friends for a week, and I want to know if it would be safe to bring him with me. He has traveled before, I brought him home from a wedding I attended (they wanted to flush him!) and it was a three-hour drive. This trip will be three and a half hours and I intend to take his tank with me so when we get there he will have his normal home environment. I have the betta cup that he came in, my plan is to fill that with water from his tank and put him in there for the journey (because that will fit in my cupholder and it keeps him from getting sloshed around too much), then when we arrive I can move him back into the tank. Will this be too stressful for him? I love Amadeus (the betta) and I really don't want to do anything that will hurt him!
