My fish appears to have intestinal worms or some kind of internal parasite.
After a lot of searching and a couple of visits to the pet shop, I've been unable to find any medicine for it. Only for external parasites.
Medicines like Paracleanse, General Cure and PraziPro (made by Japanese brand Hikari), are nowhere to be found.
Is there anything available in Japan for internal parasites in fish?
