i have had my jack dempsey since he was an inch and he would eat pellets but around the 2.5-3" he all of a sudden stopped eating them. he didn't eat for 2-2.5 weeks then i gave him some blood worms and he ate them. So i have now been giving him a varied diet of mysis and black worms. he now is 5". I have tried everything from starving him again to home made food and pellets. i have tried 3 other different company's pellets but he wont eat pellets. i have even soaked them. so would the black worms and mysis and as a treat krill, would this be good for him for life?
