Brad B. ( not to be confused with Brad Bortz) This time of year, If you are feeding your b-gill and have a good sub straight for reproduction, you won't have to worry about crawfish eating your b-gill eggs. Bass hang around b-gill nests constantly and will eat anything that it can easily get it's mouth around!!!!! Crawfish don't move fast and they are easy pickin's for a hungry bass. I've even seen them swipe at b-gill circling a nest. A b-gill will guard it's nest until the eggs have hatched. Only if a fish leaves it's nest will a preditor have a chance to eat the eggs... That seldom happens! So don't worry! Stock as many as you want cause they are hard to establish. They like soft mud, or rock's. Baseball to softball size or larger. Hope this helps. Good luck ;\)
