Actually I think it might be shrimp!!!! Which would be extremely weird because I haven’t had a single shrimp in my tank for at least 6 months. The only shrimp that has ever been in my tank was a pistol shrimp and it got eaten by melarnus at least 6 months ago.
Sorry for the blurry pics, best I could do cuz the lights are off

The reason I initially assumed it was hermits is because I have a sneaking suspicion that hermits have breed in my tank before. I have only added 10 blue legged hermits to my tank and currently have about 20 but I wasn’t sure if maybe some came on my live rock. I feel that would be hard to miss tho when inspecting the rock.

Without extensive preparations they are unlikely to survive, this is true of most things that breed in marine tanks. A couple people have bred hermit crabs successfully in captivity, generally a side project of marine breeders. I believe they are similar to cleaner shrimp, Kreisel for the pelagic stage, pods, rotifers and baby brine, as first feeds dependent on size of the larvae, need tiny shells like puka shell during settlement.
http://mbisite.org/ is a great source for marine breeding.
Hard to tell from the pictures would need better magnification to get a clear ID. could be a mysid as those sometimes pop up in our tanks. there are pics identifying both shrimp and hermit larvae in the forum of the MBI site.

Aw man that stinks lol, how long should they last for assuming they are hermits?

Awesome! I just had a similar bloom in my tank last night, did a little digging, and here's what I've come up with.

Here are photos of what spawn out for me, and what they looked like in the tank:

Here's a link to another forum discussion, with a link to a youtube vid and a photo that is nearly identical to the one I took, and some additional info about the larvae:
