Oh yeah! We are already seeing in our Pyxie's that love roaches.....they REALLY love them!!! These are the ones that are growing at a more rapid pace as well. Some of them are hesitant to get on board and only want to eat crickets. It's strange how each one has their own personality and favors one food over the other. One of the females completely hates me!!! She will raise her head almost completely back and look up at me after I place her in the feeding bin. She will then fill up with air and strike at my finger when I put it in there. It is hilarious!!! As far as the hissers, I am kind of excited to get them just to have them myself. I want to see what these huge adults look like. I won't be feeding those for awhile anyways since their exoskeleton is so hard but we will begin feeding the babies and juvies out in December it looks like.
