Not sure, but you could ask over on the cactus and succulent forum. Be forewarned, however: you will get advice about the improper pots and potting mix you are using. Don't buy anything until you have pots with holes and fast draining mix. If you are interested in succulents, take time to read on that forum and ask questions; you will learn so much, as I have. You have some nice plants there, and with proper conditions they will thrive. I don't mean to criticize, just trying to be helpful.
