Both zebrafish and guppy are better to feed. Both of them belong to small tropical fish that are easy to feed. They have strong adaptability to the environment and can survive in poor environment, so they are both fish that are less difficult to feed. However, they also have different characteristics. For example, zebrafish has stronger cold resistance than guppy, and its requirements for water quality are relatively low. Guppies have strong breeding ability, and the amount of breeding is also relatively large. Breeders can choose the fish according to their own conditions.

1. Water temperature: Zebrafish and guppy belong to tropical fish, and they need a higher water temperature to grow better. When rearing artificially, the water temperature can be kept at about 26 ℃. If conditions permit, a heating rod can be installed to keep the water temperature constant.

2. Water quality: Zebrafish has no strict requirements on water quality, as long as the water quality is clean and refreshing. When raising at ordinary times, you can change water once a week. Guppies like weakly alkaline water quality, and breeders need to keep the PH value between 7.2 and 7.4.

3. Feeding: Zebrafish and guppy do not have very high food requirements. When rearing artificially, you can choose a variety of foods to feed together. This can not only make their nutrition more adequate, but also ensure their nutrition is more balanced.
