Well title says it all. I had been feeding flake aswell but it seems a few of the fish have gone off flake since they have grown considerably and I dont think my Tiger Botia has ever eaten it. I also do my own food of Lettuce, Cucumber, froozen blood worms and frozen prawns all blended together. Will that be ok everyday in the morning just adding a serving of prawns in the night, forgeting flake totally?
