I agree with the above poster. My male has been off feed for a month and a half, one of my females have been off feed for 2 months, and another one of my females went of feed for a month and is now eating everything i can throw at them. The male and normal female went off within 2 weeks of eachother, one month later than the female, that has started eating again. I wouldn't worry about it for another month or two.
Cheers.
