I just noticed today that there is some life in my Betta tank that is not of the betta species but visible to the naked eye.
What in the world are they, how did they get there, and are they harmful?
They're incredibly small. Like visible with out magnification, but just barely. They're motile. They sit all spread out on the glass, crawl around it sometimes and occasionally I can see some swimming through the water (they almost just look like they are drifting.)
They look like something you view in a depression slide in a biology lab.
Soooooo weird. I've never heard of this. Any insight?
