Would an African Fan Shrimp (which can be colourful, not all are bland) be more appropriate, given they have no claws?
Never seen them before but I found this, so if the original question of introducing them to an mbuna tank stands, then probably not, think my bigger ones would at very least pester it to death if not actually target it for elimination
Provide a tank of at least 20 gallons.
The tank should be heavily planted and have many hiding places, because the African Fan Shrimp is very shy and likes to hide during the day.
Do not house it with crustacean-eating fish such as large cichlids, puffers and loaches, because they will usually make short work of this shrimp.
Despite its extremely fearsome looks, the African Fan Shrimp is completely harmless to all its tankmates, even fish fry. They are peaceful among themselves and can be kept in groups as long as each one can have its own hiding place.
These shrimp are very hardy and can adapt to most kinds of water conditions, provided they are clean.
It does best when the pH is about 6.5 to 7.5, although it can adapt to pH ranges beyond those as well. It prefers moderately hard water, but can do well in soft water aquariums.
Feeding: The African Fan Shrimp feeds using specialised fan-like appendages near its head to filter small food particles from the water. If kept in a well-established planted tank, there is usually enough suspended particulate matter to feed the shrimp. If, however, it does not appear to be getting enough to eat, a turkey baster may be used to squirt some zoo- and phytoplankton near the shrimp when it is in the feeding position. Because of the shrimp's nocturnal nature, this may need to be done with the tank lights out.
