Rainbow sharks and guppies can be mixed. As tropical fish, they have similar requirements for water temperature, which is 26-28 C. Guppies require water with a PH between 6.5 and 7.5, while rainbow sharks are not strict about PH and can survive in this PH range. So they can live in the same kind of water.
In terms of the types of food, most foods, such as red worms and yellow mealworms, can be eaten, so they can be fed. In addition, rainbow sharks can also be used as cleaning fish to eat food debris and algae. At the same time, breeding these two kinds of fish will also have a better ornamental effect. However, it should be noted that in the process of polyculture, we should pay great attention to the density of polyculture and the size of fish. If the size difference is too large or the number of rainbow sharks is too large, the phenomenon of rainbow sharks eating guppies may occur.
Rainbow sharks can be mixed with betta. However, a larger tank should be used in polyculture to prevent them from fighting for territory. In addition, when choosing fish, we should choose fish with similar size. Don't raise a big rainbow shark with a betta, or the rainbow shark will bully the betta.
