After doing a Water Change, while I was filling up the tank, I noticed these tiny white bugs jumping around on the surface of the water?! Does anyone know what these could be? I have a quick video of it....I'll try to post.
They are called springtails. They thrive in moist environments (they are not aquatic, just like moisture, which is why they are at the surface of the water. They can also live on land as long as there is moisture).
They are not harmful and likely your fish will eat them as a snack. Not really any way to get rid of them IME, and periodically I have them disappear then reappear for seemingly no reason.
