You just have to stick with it. I have a frog(Carl) that I have had over a year. He was a little punk for some time, the female I bought at the same time is not 4 or 5 times his size. He eats well now and no body in general pop tries to eat him, but by far my tiniest frog. Glad I kept him though, he has a great personality and a beautiful reticulated pattern.
