Typically a goldfish will lose scales if it's bumped into something in the tank hard enough to tear scales; take a closer look at your decorations and remove anything with sharp edges.
If there are many scales missing in multiple areas on the body, or you have nothing that could cause the loss in the tank for decorations, then it's possible that the fish has a parasite that you will need to treat.

∙ 16y agoFin rot is the most likely cause of this. If they are literally rotting away, possibly with white or fuzzy edges, it is almost a definite. Causes of fin rot are bacteria combined with poor water quality. Test your water, make sure your ammonia, nitrates, and nitrites are at exceptable ranges. Correct any issues with a water change of no more than 20% each day if required. Test your water 24 hours after each change before performing another. Products such as AmQuel can bring your ammonia down to 0 also. Make sure you are changing your filter media every 2 to 4 weeks, depending on how heavily stocked your tank is. Once your water quality is good, treat with an over the counter antibiotic, which you can find at your local fish store. This disease must be handled immediately, it can and WILL kill your fish.
