Larger White Specks are Usually Flukes
Ich looks like table salt, very small dots of white.
When you see white spots that are kind of in ‘crevices’ of the face and around the gill cover, and the white spots or sort of “big” or raggedy looking, those can often be literal FLUKES that are large enough to see with the naked eye. A microscope can confirm this EASILY.
The following is a 16 ounce bottle of Prazi Pro which is more than the guy with the 20 or 30 gallon tank needs. But, if you look at the pricing on 8 ounces, it’s about the same. And this size is available shipped prime, so it’s the best deal of all because you can get it tomorrow.
