Tiger-legged monkey Frog - acclimation process

[Heuchera]

Alrighty...bad news. No crickets went missing last night.

I read online that they feel safer if you put a towel over the cage, so I ended up doing that last night for two reasons 1.) to make him feel safe and 2) to keep the temp up slightly (with the light off it wasnt going above 70). I spotted him soaking in his bowl last night, but it did take him a while to wake up. Lights go off at 7, it was maybe around 10 I finally saw him move from his spot.

He is looking pretty lethargic on the whole. In sort of a last ditch attempt I tried tong-feeding a slightly larger than 1/4" cricket (since that is what he ate the first night I had him), but he barely attempted to open his 3rd eyelid and very sluggishly moved away from the cricket. tired and annoyed, basically.

I'm reading wildly different types of information online regarding the humidity, and i'm hoping if i can get that sorted out then he will be all right. For his species, some care sheets are saying 30-50%, some say 60%, and others are saying 80%.

Here's the schedule he was on all day yesterday:

Day:
Lights on at 9am - sprayed enclosure (distilled water)
Temp range 75-78 degrees
Reptiglo 13W bulb for UVB (through mesh) 10 hours
Humidity range: 60-80%

Night:
Lights off at 7pm
Temp range 70-76
Humidity 70-80% (I dont know why it was so high, i opened the bottom vents more to try and counter the towel up top)


He is still a very dark green like last night. I did open up his cage during the day to insert a fake vine, in case he didn't have enough climbing room with the cork bark pieces. Could it very well be stress that's preventing him to eat, or something worse?

I'm considering emailing the guy who gave him to me; he told me their care is generally very easy, they like high humidity and my set-up looked perfect. I'm starting to think their care is more advanced than what I have and I am slowly killing this frog without intending to. :'(

I'm attaching a picture of the enclosure, you can see my little guy sleeping in the middle. Also as a note: he is not sleeping with his legs tucked underneath him this morning. :'(
