Sorry this is going to be rushed due to time but:
What are you currently trying to feed?
What was it eating when you bought it?
How many times did it eat before you bought it?
What are your ambiant air temps in the tank?
20 Gallon tank is too big for a baby, get a smaller tank or fill it up with newspaper to take up space.
You have a pic of your set up?
What substrate was it on when you bought it and what are you using now?


These are quick thoughts. Sorry for rushing through it...
