My only garter Jake, which you'll identified as eastern (who somehow wound up in my care in LA) hasn't eaten in several weeks. Usual diet had been salmon and nightcrawlers. But hasn't taken food in about 3 weeks. Should I be trying something different? It seems like from other posts they can be hard to feed. Should I be concerned? Any recommendations?

Jake appears healthy otherwise, but restless. Sleeker and bigger since first got in June.
