I'm having the same problem with 2 of mine. I got my male pastel & female normal pair 2 weeks ago & the female ate for the guy I bought them off of but the pastel didn't. I've offered him food the last 2 weeks & he's not even interested in it. My female het pied is doing the same thing. I've offered both live & frozen thawed with no luck. The temps & humidity are all where there supposed to be. Am I doing something wrong?
