I adopted a russian on sunday, he is full grown age unknown. So far he won't eat, I've only had baby hermanns up till now which have always eaten. Is this normal? will he be ok? he's in his own enclosure which i'm keeping about 75...with 90 under his light (which he doesn't use since he just hides in his log and won't come out). I have tried lilac blossoms, dandilions, romain & red leaf lettuce....any ideas?
