the only way for aliens to live on Neptune is they have to be able to survive on a planet like neptune. it wouldn't be a very good choice unless the could live on a freezing and mostly gas planet.
Nothing
You call them Aliens Extratrestrials and Neptunians.
There are no aliens known to exist anywhere, including Neptune.

If you got to Neptune and survived you would find aliens. The aliens would make you their slave and make you tell them the Earths military secrets. then they would come destroy the earth.
