Nice set up, Kristi, and very nice succulents! I also have Ledebouria and at least one Scilla.
I know what you mean about not letting anything die. I'm the same way.
I try to keep some of them on the smaller side. I love Euphorbias! Not always easy ones to keep small.
I have a few succulents in the "gifts" category that I simply can't eliminate either.
My succulents range from smaller to larger:

The little Fenestraria started blooming yesterday.
