How long does cooked pasta last in the fridge? I sometimes cook more pasta than I intend to eat or use at once and store the rest in a container in the fridge (just plain, cooked pasta). How long would it store safely for?

In my experience, it gets some slimy mold stuff on it. If it feels slimy, its probably not good to eat, although the mold might taste delicious, you never know...
