It is very small to correctly ID. Was it always so small? If not, do you have 'before' photo? In 4 mo, it should be quite a bit bigger.

What I can tell you for sure, it needs to be repotted into much better substrate; in a clean pot (same one is most likely plenty enough in size but needs/should be washed thoroughly); pot should have drainage holes (I am assuming this one does); pot should be filled with mix much higher so plant is not lost inside of it (not helpful for few reasons); and it needs plenty of sun. If you are able and willing to make these changes - plant will grow and soon could be ID-ed.

Btw, all improvements I pointed out would apply for growing almost all succulents, regardless proper names:)

Thank you and from the before picture the only part that has really grown was the leaf and more are beginning to appear

Thesucculentgreenhouse, there is that vlog again. Can you please stop spamming us? If you can help, just do it here, like all of us.

Rob, Rina gave you excellent advice. The plant is just too tiny to ID, it would only be guesswork.

I am not sure, but is there water on it? Succulents are low water plants. If you keep it too wet, it may rot. It is potted in pot that is too large, and it is very deep inside - you need to add more mix so plant is sitting much higher.

Maybe that is the problem (too wet) - as I said, it should be much bigger in 4mo.
