My male albino is about the same age as your pastel and he just got off his 9 month hunger strike yesterday. When I first got him, he was my best eater. Never missed a meal and was always eager for 2nds. Once he reached that dreaded 1k mark, he wouldn't even think of eating. I always tried every week and offered him his usual f/t small rat and he finally took it. He lost a little weight but not much. Keep offering and eventually he will eat. Good luck and keep us posted.
