This is an excellent group for all your questions and concerns regarding bearded dragons. There are members in this group who's knowledge far surpasses any vet we have in town when it comes to bearded dragons. There is no other group like it.  It is not a show and tell group period.  It is for the health and well being of dragons.  Only post questions regarding issues with our dragon or how to properly care for it.  It's run by the lady who owns the beardeddragon.co store. I believe she's a breeder and a genius when it comes to beardie issues and makes many of the vitamins she sells on her website. I was referred to her and her website by many very knowledgeable beardie owners and she is amazing!  https://www.facebook.com/groups/103861156347217/

This group pertains to ball pythons. Never really thrilled about ball python groups or care sheets as they encourage such small enclosures with little accessories. In my experience it's not the small space they need but rather the security. Give them space and branches to climb around on along with hides and greenery for added security and they will be quite secure, happy and get exercise. https://www.facebook.com/groups/BPOwners/

This group is incredibly knowledgeable when it comes to boa constrictors. This group is mainly for BCI's and BCC's. Not a general boa group.
