This may be silly question but how do you train a brand new fish (guppy) to eat food? Also, how much flake(s) to give him given his size is about 1.25" (top of the nose to end of the tail). We got the fish this past weekend and we are trying to feed him 1 flake in the morning and smaller flake in the evening. First of all, the fish has no idea that we are feeding him. He swims around the tank and after 5 or so minutes finally finds the flake either still floating or down on the gravel and its it. Today was the first morning when the fish did not eat the flake at all even after finding it. I am assuming that we should just stick to morning feeding and skip the evening one but want to confirm.
