No. I was told to not give him d3 every feeding so i got one without d3. I think ill try the light again. Its just strange. Hes always been a hardy eater. Nothing has really been changed. He just up and chose not to eat. He always seemed like a healthy happy little dude and since he always stays in his darkest hide when i open the curtains in the morning i just kind of assumed he didnt care for the light. Ill put his light back. Its a shade dweller 6 or 7% ill have to look.
