I started hand feeding Optimal to my BG about two months ago. While I see some eating it, I do see a lot of them spitting it back out. I'm only there on weekends so they only get it a few times a week. The majority of it gets eaten by CC and turtles. I've got native BG that are not pellet trained and some Ots CNBG which I assume are the ones that don't spit it out. Guess I'll just keep throwing it out there see if they take to it.
