In aquariums, most tropical fish can be mixed with river mussels, and river mussels do not pose a threat to the fish. For example, common tropical fish, such as guppies, goldfish, neon fish, etc., can be mixed with river clams.
In addition, some native tropical fish, such as rainbow crucian carp, peacock bass, tricolor angelfish, etc., can also be mixed with river clams, but it is necessary to ensure that the water quality of the mixed culture is suitable for the survival of both organisms.
It should be noted that some tropical fish with special habits, require special water quality or are particularly sensitive to water quality, such as sandwich meat hooks, angels, Wendy fish, etc., are not suitable for polyculture.
The above information is for reference only. If you still have any questions, it is recommended to ask professional aquaculture professionals.
