I went to the drugstore and bought compound sulfamethoxazole (one yuan for ten tablets) and erythromycin ointment (one yuan for one tablet). The owner of the fish shop also ordered three cephalosporins to be put into the water tank. Don't feed the fish during their illness.

Drug the fish.

Wash your hands in advance, then fish out the Luohan fish from the water, grind it into powder compound sulfamethoxazole, and stick it on the rotten hole of Luohan fish with a cotton swab. After applying compound sulfamethoxazole, take erythromycin ointment and fill the wound with medicine.

Put it back in the water tank.

The coated arhat fish was put back into the water tank. Because of his illness, Arhat lost his activities, and the lively fish suddenly became quieter every day, which made people feel uncomfortable. Insist on applying medicine to arhat fish twice a day. It usually takes three days to see the effect.
