I had gotten my girl from a breeder, who never fed ft, so when i got her i had to switch her.
i fed her live for her first 2 feedings and she ate well, then i offered ft she refused. I let her go a week and tried ft again. She was hungry so she ate, after that she ate ft 5 weeks in a row, then went into shed, and went on a hunger strike for 8 weeks. The past 2 weeks she ate live and next week i will start ft again. Hopefully she'll switch back to ft. If not then i guess i will have a live feeder. So the best laid plans often come with a few wrinkles.
