The epi cuttings I received on May 4th have been growing like crazy. Some have grown new arms 8" long. I don't know if this is good or not, lol. Can they grow too fast, and should I cut them back or anything?

This first photo shows growth that looks different than the rest. It's all skinny. Is this just a regular arm growing? At first I thought it might be a bloom, lol. (More photos to follow.)
