My Giant Asian mantis shed once just fine when I had it, but the second time it got stuck halfway. I waited 10 minutes after I found it sitting there stuck. I then sprayed it with water and waited about 20 more minutes. It did not move. I freezered it. Did I make a mistake in doing so? I spray the cage 2 times every day. During it's L2 shed to L3 it ate the day before. During it's L3 to L4 shed (the shed it died during) it also ate the day before. Did I have a defective mantis?
