ok, breath in and breath out

repeat 10 times.... don't panic. 2 days ago you changed the cage, right? and today you took him out to take a pic? it is right?
DO NOT touch him at all, leave him alone, ok? it takes up for a week for some frogs to get over the stress of having new environment. IT is very important not to disturb him.
have you tried to throw in some crickets without back legs in his cage at night?
the frog seems very healthy, if it is impacted you would feel a limp on a left side.
