Hello, I was doing a water change today and when I looked into the bucket and I saw these small little worm-like things. I assume them to be leeches. The only way i could think of how they got in is that I planted some plants from a local pond a couple weeks back. This is the first I've seen of them, and none are on the fish from what I can see. Anyone have any idea how to get rid of them? Pictures are below.
