I got an adult 50/50 cal king last year, he won't eat F/T, although we have tried.
He had been eating very well, and then at the end of Oct, he stopped eating.
It is now Feburary, we have changed his tank, to a larger one.
I am waiting a week for him to get used to it and will try again.
I have offered live prey every week or two, he just isn't interested.
He did hibernate for a few weeks, but other than that, he has been active in the evenings, and curled up in a hide during the day.
When should I start to worry?
He is in good weight and did shed recently.
