The favorite food of guppies is live loach, followed by small fish and shrimp. Small loach is the preferred fishing bait for guppies, you can choose a length of 5 to 7 centimeters of the thin strip of live loach, hooked from the back of the loach, so that the loach can still swim in the water, to strengthen the effect of attracting fish. Small loach also have the habit of drilling holes, after entering the water because the body was hooked in a very painful, would like to scurry to hide in the stone holes, just sent to the mouth of the guppy. You can also cut open the loach's abdomen, and the blood water has a fishy odor, which can increase the effect of attracting fish.
