Anyone any advise on how I could move 8 goldfish - I know it's quite silly but they do have sentimental value - (quite small, the biggest one is only 15 cm) abroad? They have to go by van overnight - say 24 h - I don't suppose I will be able to take them by plane?

I was thinking of putting them in a plastic container (toybox type or IKEA recycle box) and taping the lid watertight - most probably it will be airtight (except for a small airbubble) too then - can fish survive that? Can I add pond plants and pond water to start the new pond off?

Thanks!
