Thank you very much for all your help. I've just seen so many youtube videos, for example
http://www.youtube.com/watch?v=gH-KmqwNkJY, and we were not sure how good that was for the turtle. As as my roommate said, "Just because it's on youtube, doesn't mean you should try it." Most of the ones on youtube are strictly aquatic frog, as you pointed out, once they become land based it would be rare to eat them. I think I will do more research and read up on tadpoles. I can't imagine that being significantly different than most feeder fish.
I appreciate all your help and advice.
I briefly read through the jello shot thread, it looked very interesting and I will give it a try though the turtle can be very picky, that might do the trick. Thanks again.
