Turtle mama

Hi everyone! I'm currently raising striped mud turtles and I've never had an issue untill this year; being slow swimmers and clumsy this year when I fed them tadpoles two were sneaky and I now own two baby tree frogs so I decide to keep, one appears to be a Cuban the other is green and they are both approximately 2 cm long (the green is a little bigger but the Cuban had it's tail longer) and what am I supposed to feed them, I tried meal worms and the green ate one but it seems like it was way too ...
