I just got a grass pickerel last week and it is a very picky eater. As of now it will only eat ghost shrimp, brine shrimp and feeder fish (guppies and rosy reds). I know feeder fish are not healthy and it can eat a lot of shrimp so I really want to get it to eat something else. I tried feeding it crickets but it looks at them and refuses. Are there any other foods you recommend for pickerel? And is there any chance that I can get it to start eating crickets? Thanks for the help.
