White spot can be a scary thing to see on any fish. You may ask yourself, “Can Corydoras get white spot?” and worry about your corydoras getting sick.

The truth is, Yes, Corydoras can get white spot. As sensitive scaleless fish, they can be hard to treat, But there are some options such as protozin which can safely treat white spot ich in cories.

The biggest problem with treating scaleless fish like corydoras is their sensitivity to most medications. However, they can still be treated for most diseases with more specialized medications.

In this case, Protozin has been shown to work really well for corydoras without messing with anything else in the tank.

Unlike other white spot medications, it’s not hard on the cory’s gills and can be used in any tank size.

It will also prevent the white spot from spreading to other tank mates in the aquarium which could easily come in contact with the sick corydoras.

If you are seeing white spot on your corydoras, it is best to treat them as soon as possible. Waiting too long can result in the disease being harder to cure and even death in some cases.

You can also treat ich without medications by bumping the temperature of the tank to 86F for about a week. Do plenty of gravel vac’s to pick up any ich parasite hatchlings the entire time.

You can also add aquarium salt to your freshwater aquarium. Salt dosage will depend on the types of other fish you have in your aquarium and can range from 1 tablespoon per gallon to 1 tablespoon per 5 gallons. Be sure to get it right.
