feeding tree frogs

[kidchameleon]

i finally got my r ed eye tree frogs. they are both young, 7 weeks old. their breeder said they are eating fruit flies and pinheads. well i have a question about feeding them. since they are so small, and their food is so small, should i feed them from a container? that is what i did last night, but im not sure if they ate any. there were a lo of crickets in the container, and the guy said they'll only eat about 2-3 a night, so i didnt really notice if they ate or not.
