Not rare but they are very unique! That's for sure!

Salt is quite bad for gerbils, they will have the right amount provided in their usual diet to not have to have extra salt given to them.
not at all. its actrully good for them too. gerbils teeth grow continuously and when gerbils eat cardbourd it help knaw them down.
When it mixes with the chemicals in their urine it produces carcinogenic chemicals.
No there not at all but there a bit better a running.
gerbils can come in many colors such as brown and white which are very common. although there are other colors which are a bit hard to find such as black, tan, grey,blonde and if you breed gerbils multiple colors
Various colors such as white, brown, black and caramel also mixed like white and black.
I would take it to a vet right away. When gerbils don't eat it's usually a bad sign.
Black gerbils are not rare. They just might not be in your pet store because i have seen many on youtube.
