The best foods for your ADF's are HBH frog and tadpole bites, frozen bloodworms, frozen mysis shrimp, and frozen brine shrimp. If they are in a species only tank, live foods are great for them as well. Avoid other pellet type foods, because yes they will constipate frogs, and all dried foods.I just got my 2 frogs and was wondering if mealworms or wax worms are a good diet for them.
