I am a beginner. The Cainarchi Imitators I got from John seem to be doing well. They seem to be most active in the morning, although as of the last few days...the one has been out and calling into the night. Really soft pleasant call too. A few days before I received them, I read somewhere that you really have no idea how small they are until you see them in person. Very true. I opened the box and was like, jesus, theyre smaller than the crickets i feed my bearded dragon. I forgot to post this story when I got them but the ups guy actually did a flip with the box as he was walking up to my front step. I wanted to punch him.
