Not up on frogs but I hear they are messy, but the mix looks good . . . I'd be a little wary about the flying fox . .. they can be territorial. They would be easier to keep though than the shrimp. For the Amano Shrimp to be effective as scavangers, Takashi Amano suggests 1 shrimp per gallon.
You might do better with Siamese Algae Eaters, or Oto cats . . . a couple of each and 2 corys. Personally I like the julii myself. If it's true that frongs are messy, you might be a bit overstocked. Maybe someone else has another take on that
