See through looking worm?

Hey guys, transplanted one of the plants earlier, not sure if this guy has been in here or if it happened to get in there the hour this now empty cup sat there, look like a thing to worry about more being in the soilwith the roots? I did have a small amount of algae show up, guessing from the clear cup part. Watered with 20.8 C degree water with bionide liquid root stimulator after transplant to help any algae in the soil GTFO.
Best pictures I could get of the little guy

Looks like a fungus gnat larvae to me
