The successful feedings were exactly what I'm still doing. I put him in his deli cup, and add a f/t pinky.
He ate the first two times and not since. I didn't change anything about the way the food was offered.
I was planning on waiting a couple of days before trying again, I know it could stress him further.
I also on the suggestion of the breeder I bought him from raised his temps slightly. He was at around 75 and she suggested I raise him to 80. So I did.
