When looking at the video PacmanFood, I wanted to copy something similar to give as food occasionally. Use balanced food of American Bullfrog. (Frog extruded). The problem was that frogs defecate very liquid and very ugly smell.
I returned not to use. Studies on ancient items found in stomachs of C.ornata conclude that their main diet is other frogs. As provided in captivity? Frogs healthy, disease free and cheaply, very difficult.
I only use cockroaches, crickets and earthworms as based diet. every 2-3 months a mouse. But I think it lacks the nutrients that food provides the other frogs.
Sorry for my bad English.
