The only problem I have had with feeding my AFB's is the size of the food. I tried giving my newest pixie a superworm that intimidated him. He was a bit skittish for a couple days after that as well. But he got over it and, in no time, was eating the right sized food with furious anger.

Ok, I take that back. There was a time when I was switching one of my frogs to different aquariums, trying to figure out how to divide up the population. He got nervous and didn't want to eat for about a day.
