Is this hitch hiker dangerous? Is this a parasite?

Okay so I got a few new plants for my goldfish tank, and when I presaged in water, I saw these little things moving. They look like baby shrimp but they might be a parasite. I soaked my new plants in hydrogen peroxide to clean my plants. Previously I used 1/21 bleach but then it killed my anacharis because it was such a fragile plant. This time I got more anacharis but I don't wanna kill it will bleach again so I'm using hydrogen peroxide. Anyway, it killed the germs but it didn't kill the shrimp like parasite thing. Is it harmful?

Looks like a scud, although a closer pic is needed for full confirmation. They're harmless and a common inhabitant in planted tanks. They also make good treats for most fish.

Yeah, that's a scud. They are harmless, I have a growing colony of them in a tank with my baby RCS and they are all still alive. They are also great live food for your fish, though the goldfish will probably make a appetizer out of them

Scuds are one of the few things that will devour thread and hair algae.
