Do not take dry food out of their diet. Since our frogs live in captivity, we cannot always ensure enough variety that will cover all of the frogs' dietary needs. Also, dry food has the correct ratio of D3 and calcium. While some ADF will not accept dry food, I think you should always attempt it. When I kept ADF, I noticed that they preferred the specially formulated Xenopus Food from Xenopus Express over Frog and tadpole bites. I strongly recommend you look into feeding Xenopus Express' sinking pipid frog food.
