I bought him/her on a bit of an impulse. I already have all the habitat all set up, but I seem to have lost the leopard gecko forum I was using as a reference.

1) What do I use to gutload the mealworms?
2) If I am dusting with a calcium/d3 supplement do I still need to include a dish of calcium powder?
3) How often/how much do I feed a juvenile versus an adult?
4) How often do I dust prey for a juvenile versus an adult?

The little guy/gal I bought is black and gray with no apparent yellow. What are some common morphs that he/she could be?
