It's hard to tell, so consider taking a better photo. If possible, a camera with a good macro setting may help to take a closer photo.

However, does this look like what you've got?

Planaria are often found in aquariums with uneaten food. The planaria won't hurt the fish, but they are a symptom of too much gravel containing too much uneaten food, and that is not good for fish. They require a food source, which means there must be excess food wastes in the tank to support them.

If they've been living on the food/waste in the gravel, it's possible you didn't notice them until you cleaned the tank. You remove the food, they move around more?
