I got this cactus a few months ago and it seemed to be doing well- it sprouted up to how tall it is now. . Is it normal for cactus to kind of shrivel this way? I'm not sure what the issue could be. Too much/not enough sun/water? Should I re-pot it or would that put him into transplant shock? Any ideas on what I did wrong or how to save this little guy? Thank you..!
