Adult guppies can be fed 1-2 times a day, but the specific feeding amount depends on their feeding state and living water temperature. If they live in high water temperatures, their metabolism will increase, their demand for food will increase, and breeders will need to increase their feeding frequency. If the water temperature in which they live is low, their appetite and activity will also decrease, so breeders should also reduce the frequency of feeding to avoid food residues affecting the water quality.

In addition, if they don't eat well, breeders should reduce the frequency of feeding to avoid them eating too much. If they eat well and still forage after eating, breeders need to increase the frequency of feeding.

Adult guppies can eat within 5 minutes at a time, because they are mature and do not need too many nutrients and food, so try to feed them to 70% full. The specific amount of feeding should be decided according to their eating situation. If the feeding food guppy has not been eaten, the breeder needs to fish it out immediately to avoid the residual food polluting the water quality. If they have obvious foraging behavior after eating the fed food, the breeder needs to increase the feeding amount at the next feeding.

There are many kinds of foods that guppies can eat in adulthood, and breeders can choose a variety of foods to feed together, which can not only ensure their adequate nutrition, but also improve their resistance and immunity.
