I have many reptiles and I am soon to get some PDF's. I was wondering about feeding. I know they eat small things. Would pinhead crickets be appealing to them. Is that a good food source for them. Also, how do you culture Fruit Flies. I know when you buy a culture you get everything you need, but I dont know what to do with it, how long the cultures last. How many flies to put in the tank. I have a 30 gallon long that is going to be a vivarium. I am getting a group of leucs or something else. I dont really know yet. What PDF's are good group frogs. I am going to get 4 of them, whatever they turn out to be.
