Western green toad won't eat HELP

[elly]

60F is low for most frogs. I'm not familiar with the species, but I imagine it would slow his metabolism down a lot so he'd be sluggish and want to eat less.

Any advice on temp , humidity and lighting ?
Also are they nocturnal , he seems to be more active in the afternoon
can I put a canopy on top of his tank with lights in ?
