I have a senegal whose with me for over a year now and has been pellet trained since I got him. He eats shrimp pellets, sinking carnivore, massivore. But since last week he seem to be interested only in superworms or market shrimp, he doesn't accept my diy food either and in the past he will eat it like a monster . Do you guys know how to make him eat pellets again? will starving him do good?
