Fish that are already infested by gill mites are brought into aquariums. The tiny mites stay on the fish’s gills, and attack the fish by feeding on blood and living flesh.
- Gasping at the water’s surface
- Gill covers that are partially open
Initial treatment with sterazin is recommended with a secondary treatment of octozin to cure the fish once the mites are gone and help the gills get back to normal.
It is often advised that you should keep tropical fish in a quarantine tank before introducing them to your main tank. Although this wont prevent gill mites in the fish you may have purchased with the disease, it will stop it spreading to your other fish if you are able to observe them and treat them before introducing to your main aquarium.
