The extreme fire shrimp and black shell shrimp put together mixed culture is no problem. Because they all belong to rice shrimp, their habits are similar and their requirements for growth environment are similar, they can be cultured together. In addition, they are relatively mild, not easy to attack other live shrimp, so they can also live in peace. They are omnivorous shrimps with similar food requirements, so they can be raised together.
extreme fire shrimp and black shell shrimp mixed culture will be a string of species. Because they are so closely related, they can breed with each other. In this way, the shrimps will be planted. If you don't want them to cross, you can't breed them together, and it's better to use two separate tanks to breed them. If you don't care about string seeds, you can put them together.
Extremely hot shrimps are relatively easy to be mixed with. If you do not care about the string of species, then it can be raised with black shell shrimp, cherry shrimp, tiger shrimp, bee shrimp and other rice shrimp. If you don't want to cross seed, it is recommended to put it in the same tank with crystal shrimp. Because these two kinds of shrimp are far away from each other, they will not mate and reproduce, so they will not cross species.
