Yes, alive is good, the kicking motion attracts fish strikes. If you buy many at a time they are easy to keep and breed in an old leaky 20g in your garage. You can also gutload feed them with high protien foods and vitamins and mineral supplements for your fish. They are healthier than goldfish and if you match the crickets size to your fish they will be taken by almost everything, even picky eaters.Oscar guy said:Can i feed em alive?
