Pet problem. Can you help?

My husband and I live in Washington State and we're moving to Arizona in about six months. We recently got pet African Dwarf frogs with a guaranteed life span of about five years. There are fish in with the frogs also. We also have a beta fish. Now, we're planning on driving to Arizona, but we don't know what to do with the fish we have. (we also have a cat and mice.) How can we travel with the fish and keep them alive for the three days it will take to drive there? We were thinking of just putting them in a bucket or something, but do you have any better ideas? I know this problem is probably ridiculous, but I was just seeing if traveling with aquatic animals is a good idea in the first place. Can you help us?
