My neon tetras have white spots. Could it be ich or a fish disease?

Pet's info: Fish | Unknown - Fish

I noticed 2-3 of my neon tetras have very few tiny spots on the top of their body and or tail, that are a white color. I noticed it tonight and wanted to know if anything is wrong with them. Their behavior hasn’t changed at all from how they act since I’ve gotten them a week or two ago. Should I be worried?

The tiny spots could be a parasite infection. Ich presents as small dots similar to grains of salt. It will quickly overrun a tank and can kill fish if left untreated. You will need to treat the entire tank as opposed to just affected fish. A broad spectrum parasite medication that covers ich can be purchased at the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.
