I have a BP who I'm trying to switch to F/t (have had him for 2 1/2 years) so I've had to feed live for a while. If you need live feeders check out Petland, you have to ask, or look up Brooklyn Zoo and Aquarium. Not sure where you live in Brooklyn but I hope this helps.
Note: Brooklyn Zoo and Aquarium workers were always friendly to me but they have a horrible reputation. Animals are not kept in great condition and I took my business elsewhere once I found an alternative live feeder.
