Can I bring live fish to china through tsa?

Sorry, you can't.

You cannot bring live fish to China through TSA without proper permits or documentation. China has strict regulations regarding the importation of live animals, including fish, and you will need to meet specific requirements such as health certificates and permits. Without these, live fish will not be allowed to enter the country.

Additionally, TSA regulations also require that live animals, including fish, be transported properly in containers that allow for inspection, but international customs rules, like those in China, are the more restrictive factor.
