Got 11 discus varies from 4 inches to 2.5 inches and had been feeding them 4 cubes of bloodworm 3 times a day plus some pellets
in between but they seem always very eager to eat again. So how much to feed them in order not to overfed them?
Congratulation! You have healthy fish.
Feeding 3 times a day should be enough.
Every time they eat all and no left over.
Over feeding with left over, will pollute the water.
Over eating will stress the fish too.
