Thanks for reaching out. If is a good idea to fast for 1-2 days prior to shipment, this decreased feces and will help to keep the ammonia down. Typically clear bags are utilized with about 50% water, and 50% air/oxygen used. A local pet store might be able to assist, as they get shipment in (so have older bags and boxes, which need to be disinfected) and hopefully the skills to ship. Check with the airline also, box needs to be well labelled "LIE ANIMALS" and "THIS END UP". Sometimes a health certificate for interstate travel is needed, so contact airline and State of Utah, veterinarian. Good luck.

Yes it is possible, however, unless you have a lot of experience keeping saltwater fish, please do not even attempt it. Most wild caught saltwater fish will not feed when they are in an aquarium, and only a small percentage will ever learn to feed. Please leave them where they are happy and healthy and where they belong, the sea.

The fish that you are describing is Apolcheilus lineatus commonly known as the Golden Wonder Killifish. By looking at the images that were attached it appears to be a male (females are typically less colorful ).

Even though a better picture (i understand it is not easy at all!!) of it would help to determine the nature of this lesion more specifically and give you specific advices on how to give appropriate treatment, generally speaking you can follow these guidelines: - set up quarantine tank: make sure the tank is well oxygenation and has some plants for hiding; - add 1 teaspoon of aquarium salt per gallon; - add this product https://www.liveaquaria.com/product/4410/?pcatid=4410 as indicated; - leave your fish there and feed him regularly for 3-4 days until you don't see any improvement - If no results at all are seen after 4 days a check up would be needed as more specific tests may be needed to establish a specific diagnosis. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be u
