What happens when you forget to feed pacu

[Red Devil]

I only feed them pellets,fruits and veggies. The guy I got them from was into giving them the occasiuonal feeder.
I feed them on a Friday afternoon,forgot Saturday , and was back out to the shop to feed them Sunday afternoon.

well i quess this had nothing to do with feeding... i quess it would have happened one way or the other.. unless the cichlid passed naturally and then they started eating it after its demise... but after reading other incidents where pacu attacked and killed and ate other fish.. i quess this is normal afterall... i just never experienced any of this...
