my 5+ year old Russian has not eaten a substantial amount in a couple weeks. maybe a couple bites of mazuri, but no greens. i usually feed him every other day but recently I've been offering it everyday. he comes out for it but then hides again. i haven't changed what i offer for food except for adding mazuri, which he seems to like. his enclosure is always 75°+ with a basking spot of 100° always has a water dish and plenty of hides. any ideas?
