can't get guppies right now, but I did try live minnows
tadpoles are not an option either
Jeff did manage to hunt up a couple of tadpoles at a shop in the city a few years ago when I was in a similar situation; I was so thrilled when he called to tell me, but when he brought them home they were huge - much too huge for the baby I was going to feed it to - probably bullfrog tadpoles
amphibians are very hard to come by in a manageable size
