How Often Should I Feed Them?

Is every other day standard ? One fish person I spoke to said he fed four times a day, some every other day or every day. Some websites say twice a day. 😬

I tend to feed twice a day but I feed different things for example I feed flake before I go to work which some fish are happy but my loaches don't feed in the day so I feed pellets or blood worm just before bed and there quite happy to feed on it then both feeds are very low amounts abd generally both feeds are gone quite quickly
