Well ok it seems like you're set! But the crickets will hop out
You should also try hand feeding you cham or using tweezers then hand feeding it might make him/her more friendly if you want to hold it more, also for some magical reason the first day i had my cham, he zapped a silkworm right out of my palm .
im gonna try to hand feed..but therre are some food items that will take me a little getting used to.lmao...im not new to chams,i have montanes,just not a panther,he will come tomorrow,im very excited..
Looks good! I would add rocks to the plant pots to prevent him from eating dirt and add more horizontal branches. You can collect the branches from outside, disinfect them by baking them and put it in the cage.
That cage is huge for him! He will enjoy the extra space and not having to share with his siblings. Good you are cup feeding him, I would worry about him not finding his food in that cage.
The dubias are in one of the corners of the box. I would gut load the dubias before feeding.
