He was in the post for a couple of days, not sure whats up with the discoloration around the bottom, but its firm and the pups are green and firm. I dug around the root base and it looks good and firm. The soil is moist. Not sure if i should repot in a dry substrate or just leave it alone? 8-[ image...

I think this might be a petunia leptocactus, but I'm not sure.
