Help confirming of these are Blackworms or tubifex?

[JayDiscus]

Hey guys and gals! I bought a small batch of live Blackworms from the lfs and I just wanted to confirm if these are actual Blackworms or if they are tubifex? I initially bought thses live Blackworms to condition an emaciated discus that my neighbor gave me. He is much more Skinner compared to my own discus (apparently dude didn't feed his discus for 2 weeks, I'm surprised that it was even still alive honestly) Also I was wondering if freeze dried Blackworms would bulk up this discus like live Blackworms do? Thanks!

Edit: I just realized I posted this on the wrong board, I'm so sorry. Please ignore this initial post, I'll be posting this on the food section (I don't understand how I got confused between the two lol)

Hard to tell without a close up of a worm. Have you asked the store who their supplier is? As far as I know there are only two actual suppliers and both are in California.

I'll try to get a close up of the worm right now, I've asked the store a few times but they mostly role their eyes on me and ignore my question. Honestly, I don't like this lfs buts it's the only one near my location sadly
