yep that's a good pic of anchor worm.
Salt will kill that if you only have goldfish in the tank. A couple of tablespoons of rock salt/ swimming pool salt or sea salt per 20 litres of water. after a couple of weeks start doing small 10% water changes each day to diltue the salt and bring the tank back to fresh.
You can also pull the anchor worms out with a pair of tweezers or pliars. Get the fish in a net and grab the anchor worm firmly, then pull it out. Then monitor the fish for secondary bacterial or fungal infections.
The cloudy water is probably too much food decomposing in the tank. It is a common sign in tanks when the filter is not working properly, (insufficient filter bacteria to break down all the fish food and waste). Cut the feeding back and do water changes.
