I think so? But not the worm like ones, just the smaller ones. They are so tiny it was hard to capture on camera. At first I thought they were air bubbles or something, like when you add new water and the bubbles get stuck to the glass. They seem to be mostly congregating on my newly added driftwood, which I boiled for a couple hours before adding. I also added two new plants recently. Before today, I didn’t notice them.
any chance they are something to be concerned about? My fish don’t seem to be interested in eating them. I have yo-yo loaches, mystery snail, albino super red pleco, and Glo tetras. I would love to get shrimp, but I think they would end up expensive food for my loaches
