Need help identifying

It's an Echeveria 'Black Knight', not 'Black Prince'. Prince has wider leaves. It does need a lot more light, I would behead it and start over. You can prop the leaves on the lower stem.

Looks like an Echeveria "Black Prince" with a bad case of etiolation. Not entirely certain, though.

I got one for my boyfriend that looked almost exactly like yours when I was just starting into succulents about two years ago. When I started learning more I showed him what his plant should look like but he wouldn’t let me behead it because he liked the way it looked. Now just about a month ago it was losing a lot of bottom leaves and had a lot of compact growth on the top and he let me behead it. So what you can gather from this is, if you like the way it looks now it CAN survive for a long time like that and you can decide later if beheading would benefit the plant more (especially if it loses many of its lower leaves) or you could do it now. It’s honestly up to you.
