For the treatment of secondary bacterial infection, Nifurpirinol (Dose: 10-15 mg/100 l for an unlimited time or as instructed) is recommended. The treatment should be continued for at least 5-7 days in a tropical aquarium to completely kill all the spores. The fish should be in quarantine and the aquarium should be empty for 14-21 days so that all spores is completely irradicated. Plus the temperature can be raised to 28-29°C to speed up the cycle to release the spores, so that the disease can be treated quickly. |
| Quarantine the infected fish for 3-4 weeks, making sure the water quality of the is optimal. Avoid stress and other environmental factors that can promote the onset of the disease. |
| The parasite can remain attached to the gills and skin of the host fish for 3-6 days for tropical aquarium and for low temperature it can remain for 10-12 days. It can develop into a cysts as soon as it reaches its host fish, producing 250 spores that will also look for new host fish. The spores would die within 48 if it hasn’t found a host fish.
