Sorry for the late reply Neal. He doesn't really like the zoo med food but I keep mixing it with his food so I hope he will eventually develop a taste for it. Yes he poops regularly. Also today he weighed 75 grams!
So my leopard hatchling was gaining fine when I got him he weighed 30 grams and went up to 69 grams and just stopped gaining. He was housed in 48x18x12 glass enclosure with a basking spot of 100-105 and the cool side never got below 80. So he had good temperatures the humidity was 70-80...
We can't answer that with just a picture. We need more info what's he housed in? Where did you get him from? What are his temperatures? Give us some more info and we'll be glad to help!:)
