When do you last feed your fish, The Last Supper Options

[goldrush]

Today’s topic has least to do with the number one best seller by Dan Brown nor the blockbuster movie,the Da vinci code.But both book and movie centred upon one magnificent work of art by a renaissance, maestro Leonardo Da Vinci…..
The Last Supper.

With that introduction,I would like to ask forum bros here when do you last feed your goldfish for the day?………ie Their Last Supper for the day.

We are brought up here to believe in delivering small amount of food many times over a period of the day.But when do we stop?Bros who utilize green water environment stop feed by early afternoon to give the greens enough time to consume the resultant ammonia generated for the day.Does that mean practitioners of clear water have the advantage to continue feed right up to evening?What about those that feed throughout the night and day.We are not talking about fries here ,mine you.Are there advantages over the number feed in a day or are there unnecessary harm if the digestive system is not given ample time for the fish to take a rest before resuming such glutton exercise.So when should be the Last Supper for our fish. Now this may differ among countries where the diurnal period varies throughout the year. So do we give our last feed a couple of hours before sundown?Is there a recommendation where we can follow which is practiced not only by hobbyists but professional breeders or keepers to maximize growth rate with minimal damage (if any) to our fishes.
Perhaps we need the Da Vinci code to unravel this hidden mystery

All lines are opened. Let’s discuss.
