We are quite attached to Big Bertha and the boys and want to take them, and the others, home with us. They now make a kind of carrier bag that lets oxygen in through the sides and CO2 out the same way, so it's safer to transport fish long distances. I know how to pack them, and all that stuff. There is no restriction in the USA for bringing pet tropical fish (of this variety) into the country. (Checked with USDA, Fish and Wildlife, and have written to the destination state's bureau for advice as well.) They are worth a max of $10, so customs isn't an issue although they'll have to be dealt with at customs.
The problem is finding a carrier that will take them.
Supposedly TSA lets you through security with tropical fish in the USA, not sure what UK's version of same does. The problem is that even after getting the nod from security, I've had no luck finding an airline that will accept them. I've been researching extensively, and nobody I've found will accept fish in the cabin (in a carrier that goes under the seat in front) on a trip from the UK to the USA. I haven't actually found one yet that will allow a box of fish as a "pet" traveling in cargo when I fly, either, as they'll do for dogs/cats/ferrets/birds. So far all I'm coming up with is a few companies that are pet-freight forwarders.
Does anyone know of an airline that will accept tropical fish as "pets" traveling in cargo?
(UPS has a service, but it would take about two full days to get from our flat here to our future flat - that's a long time for the kiddies to be boxed. They'd probably survive, but it's not a good idea. I had the same breed of fish in a fish tank in the back of a U-Haul driving from Dallas to the West Coast in the middle of the summer, one time, and they made it just fine. But I don't want to be taking chances with them on an international shipping with something like UPS. It's also obscenely expensive - more than buying an airline seat and putting them in it, actually.)
