don't quote me but I believe you want them sitting in water, not oil. I'm using Tuna Fish as my inspiration for the answer which says the same thing.
Probably not, but I'm addicted to them.
It's a love-hate thing.
Anchovies are very high in omega 3 fatty acids, and are quite beneficial -- except, they're often packed in a lot of salt and oil to get that taste, which kind of lowers the healthfulness. You can get them not packed in sunflower oil; you either want them not in oil or in olive oil, for best taste.
They're also really good as bait.
thanks! i'm a little shy of them now cause on the weekend one got stuck in my throat, then i waited 3 days to see specialist, by which time the discomfort had gone and she didn't see anything and i was somewhat embarrassed.
i will drain off the oil - and chew them very well
