Neptune is a gas giant, so it is uninhabitable to humans.
Yes They do,Most Dogs Have it, But They Need It For The Same Reasons Humans Do.... So They Can Live

It would not be possible to modify Neptune for us to live on. It's a gas planet, so has no surface like that of the earth. It's also too far from the sun to support life, way too cold and dark.
Animals need food so they can live and when its winter as you know there aren't a lot of food around so that's why they eat so much in summer so they can have there tummies full in winter or they will die.
Well, fish need rivers, and so do the plants that live around it. Humans may also need it if it has dams in it that provide hydroelectric energy.
Its a big planet, but thats about it. Its atmosphere is mostly gas so isnt the healthiest place for humans to live. You'd also be crushed by its gravity. The good thing is that astrology is bollocks though, so you dont need to worry about the effect of it lining up with Mars has on your life.
Not so long, its made out of gas so you would fall through and probably be burnt to ashes.
