Need help with mangrove snake

[krakerlip]

Just got a mangrove a couple weeks ago it's obvious it was kept too dry for quite some time. It has shed once with me and it was a decent shed. I have the temp and humidity where it needs to be and hides plenty of space height and so on. Feeding is a problem tried fish and f/t mice Each week it has ate a ft fuzzy but only once. It didn't take it from tongs it seems to be scared of it with tongs it ate after I left it with the snake at night hasn't eaten sense then (10 days ago so not a big deal). Any one have any tips on getting this little guy eating normally and more interested in f/t mice ?
