The mixed cactus seedlings outgrew their little pot, so I potted them with my 1 year old Astrophytum capricorne seedlings. I’m still not completely sure what they are.
Oh, and remember the Astrophytum asterias “superkabuto” seedlings I never really updated on since they were 32 weeks old? There’s one left (the one closest to the camera in the top pic) and it’s now 2 years old. It never really grew since then.
