Ok, long story short, I ordered 4 fish from a a seller on ebay.  Now keep in mind these are not the first fish I have ordered and have had shipped to me, I don't like to have fish shipped to me but if I want nice healthy fish this is my only option.  Yes, I do have local pet stores but unfortunately anytime my husband and I are visiting one there is always dirty tanks, sick fish, and a lot of the time dead fish in most of the tanks. So anyway back to my story, I purchased 4 fish from a seller on ebay, 1- 2in red cap oranda, 2- 2in calico ryukins, and 1- 7.5in koi.  I purchased next day arrival and was under the impression that my fish would be properly packed for the journey.  I was handed the box 2 days later (seller shipped the morning before) by my wonderful UPS lady and brought it in, set in on the kitchen bar and opened the box.  I couldn't believe what I saw,  the seller put the fish in one bag and just put the bag in the box!  No packing or anything just a bag in the box, there wasn't even any air in the bag the top of the bag was laying flat on the top of the water.  I then noticed the koi was on his side in the bag I noticed this was due to there not being enough water in the bag to cover the koi.  I rushed to my fish tank and added a small amount of water to the bag so he was covered and could at least move around while I let the bag float in the tank so the water temp could adjust.  The koi and the 2 ryukins were going to be put in our outdoor pond but I thought it wold be best to get him in our tank for now so I could see what was wrong with him.  Lets just say within 10min of releasing him into the tank he was dead.  I was so mad, I emailed the seller and told him what happened and that I couldn't believe how he packed these fish.  He couldn't even provide the basics for these fish while they were being shipped let alone and protection for the bag while it was in the box.  The next day i got an email from the seller saying he was sorry, he would give me a refund for that fish and that he was not going to add any packing to the boxes, he ships fish like that all the time even hundreds at a time in one bag.  So back to my question, does anyone know of any laws on how fish should be shipped??

I noticed the forum you gave me was for South Wales do they also have info on shipping for U.S?  I do have pics of the koi, I have the pic the seller was using to sell him,  a pic of him at the bottom of the tank as soon as I released him from the bag (he sunk straight to the bottom), and the pic I sent the seller to let him know the fish was dead.  I have talked to other people on ebay about it and they have pretty much said something along the lines "you got your money back, whats the problem?".  This was a living animal that slowly suffocated on its way here due to the lack of care from the seller.  His motto should be "I send then as cheap as I can, who cares It is just a fish and I already have your money!"

I mentioned it to them and they said get in touch with the American animal welfare group that is similar to the English RSPCA and inform them and inform the postal service so they can ban and vet any parcels he sends from that address.

I really thought this was a reputable dealer, I checked him out before buying from him. He has been a seller of koi and goldfish on ebay since 06, he has a 100% feedback score with only 1 neg. feedback in the last year.  I even went back to read all his feedback and NOBODY has mentioned the lack of care or packing! He has 6,712 feedback, I am truely finding it hard to believe that I am the only person that sees a problem with it.  I did contact PETA a few days ago and I got a reponse from a lady there she sent me a link to USPS guidlines, so I told her my entire story and asked what I can do or who to talk to.  I am going to contact the American animal welfare group also and see what I can do. 

Oh nice! I always forget fancy goldfish can be kept in ponds XD
That 100 gall tank just sounds awesome though, you should post pics sometime
