If you don't mind me saying this: any succulent you buy & keep in jars like that will die sooner or later. In a jar/bottle like that - most likely very fast. Terrarium style containers are really bad for succulents. They may look very nice - I like the look - but are def not suitable for succulents. They do not have any drainage, humidity gets too high, when in any sun - it will get hot & stuffy there. No wonder one is already dead. I think it is really bad that stores sell or recommend these kind of 'set-up'. If you want terrarium, get one with high humidity & moisture loving plants, not succulents that grow in pretty dry & gravely conditions.

If you want to keep any succulent for any length of time, get regular container, with a drainage holes. And use fast draining mix.

That was the plan, get them, repot them to something more suitable. Was waiting on my day off to go get what I needed however it pretty much went within 24 hours.

It must have been very wet already. You'll be better off not to buy plants in those kind of containers. They could be suffering a lot - not easy to know how long they have been like that. And you probably have to pay more for the jar! I saw some tiny haws in 3" pots selling for $5. Exactly same plants potted in small mason jar (!!!) were $10...

I can't tell you what the plant was. Could have been crassula or maybe a cotyledon. Or perhaps very etiolated echveria. Could be something else. The photo doesn't show it well enough for me to ID.

Probably got wet or watered somewhere recently. Kiss of death, moisture w/out any drainage or air circulation, can kill a succulent quickly.

I agree w/ the info you've been given above, all very true.

It's annoyingly deceptive marketing on the Sellers part. We hobbiests know it's a set up doomed to fail, GGRRRRR.

One on left is an Opuntia Microdasys. If I could give you some advice the fuzzy things are NOT nice. They're called glochids and will get stuck anywhere and everywhere. They are extremely irritating to your skin. In fact I have one stuck in my finger now and it's driving me nuts. So be careful and handle with care:). The one on the right is an etiolated Crassula Mesembryanthemoides

I can see the fuzzies when I make the photo bigger on my iPad. My Crassula Mes is more like hers. greener with less fuzz:).

Thanks all :) I had also emailed the Botanic Gardens here and town and they identified it as Sedum hintonii which I think is part of the Crassula family.

Did you get it from there? If not, how did they ID it, from better photo? S. hintonii is supposedly quite rare plant. All photos I have seen show very compact plant, with pretty 'chubby' leaves & very nice flowers when in bloom. Like it...

(Cassulaceae family is quite large - approximately 1400 species and 34 or 35 genera...)
