I would handle him a bit more at the moment until you both get your confidence back. To feed him out side the viv you will need a
Herp Haven or similar to put him in whan he eats.
If you want to feed him in the viv, just use you tongs to put the food in the viv in a at the opposite side to the viv so the snake has to come and find the food and wont need to strike when it gets there.
