Tiny white critters hitched a ride on plant shipment: ???
There are some TINY white creatures that are on the plants and near the back wall of the tank. There aren't that many of them, but I'm hoping someone here can help ID them in case they're parasites that will harm fish or something.
1. They're so small that they're almost not visible.
2. Some of them move slowly across the surface of the glass (like snails, but they're not snails.)
3. Some of them move in rapid bursts of speed and then stop dead, then burst again. Like they pop from one place to another, fast.
So are these things like tiny shrimp or something? Fish food? Or are they parasites that might hurt any fish that I add?
I wish I could take a picture or give a better description. Any guesses would be great, though... thanks!
