What kinds of food do your neons prefer? I recently bought some but they don't seem to eat much. They ignore the frozen and gel food cubes. I noticed them chasing tiny particles that the other fish stir up eating them so i crushed some bug bites flakes for them and they chased them but spat them out, same for the nls micro pellets, regular and crushed. Maybe I should get them a small live food like daphnia?
