When they were fed weekly, how many minnows were they given?
If you just got them and you think they're really thin, I'd feed them smaller amounts more frequently. If all they've ever seen is fish, they're not likely going to recognize pellets as food, at least not at first. I'd offer leafy greens and try earthworms (one or two each depending on the size) if they absolutely refuse pellets to keep their appetites up. Keep trying pellets, though.
