Griff, thank you very much. I really glad I changed out his substrate. The treated tap water makes complete sense. I use my r/o on my house plants and then I add nutrients to that water. I am all about this little guy and his health/well being. I finally got to see him feed and it was amazing! Two crickets wandered in front of him (with my help) and man he nailed both at the same time! Then ended up eating 3 more in front of me. He is so cool. Oh another dumb question, will flukers high calcium cricket diet hurt him if he gets it on him? I put a cricket in before his lights came on and some flukers sprinkled out of the tube and on him. Not heavily though. I assume he will be fine...? Thanks guys!!
