Looks like tailrot but it’s gotten bad….the darker areas look necrotic. You should try to source an antibiotic like kanamycin if it’s available where you are. At the very least, you should clean your filter and keep up with large daily water changes to lower the overall bacterial load. You can also give the fish a salt bath or a methylene blue dip…or dab the area with povidone iodine or merbromin as an antiseptic.
