I don't know why, but my O's stop eating their food. If I feed them crickets and shrimp they will eat that, but it’s as if they just stop liking their food. Before they would eat their food like they haven't ate in days

now they will spit it and I live it there for about 5min and then take it out. I don't know what else to feed them. I also give them like I said shrimp, crickets and meal worms once or twice a week.
I give them: Tetra Cichlid Food sticks and Hikari Cichlid Gold Food
Any advice you guys have would be appreciated
