I agree, tarev is a lovely person.
If I were you, I would separate the pencil cacti since Euuphorbia tirucalli makes a large plant. Give them each a pot but not a huge one just yet. I see you have the 'Rosea" variety of the pencil cactus They are looking good.
The sap of E. tirucalli is extremely caustic so do be careful where you put them. And wash any sap off immediately should it get on your skin.
I'll butt out now ... this has been a most interesting thread ... I do love the succulents.
