If you read the proposed guides for importing they talk about testing for diseases where there is high risk or where there have been deaths over a certain percentage. If you have problems with 10000 neons you could possibly lose 1000 before the testing kicks in, but if you bring in 10 rare and expensive (possibly high risk) fish you only have to lose one. It comes down to risk and a numbers game. These people have to make money to stay in business and that is not easy at the moment.
You are welcome to see if there is an importer out there prepared to take it on but there is good reasons behind why many fish that are on the approved list are not imported.
These things come and go as importers come and go so it is possible that someone will come along who is prepared to give it a go. Chances are they would want good money because of the risk.
I wish you luck and hope you can get what you want.
