It is my opinion that the best method for keeping Neolam-prologus brichardi is in a species only tank. A tank as small as 15 gallons can be utilized, though between 20 and 35 gallons would be more appropriate. By keeping this fish on its own, not only do you limit the chance they will eliminate their tankmates, but their graceful finnage will likely grow much better. That is not to say that it is impossible to keep this fish with other Tanganyikans, but one must be careful in selecting tank mates, and the aquarium best be at least 90cm long (36"), with a 120cm (48") tank being preferable. Some commonly available fish that should be compatible would include; Neolamprologus leleupi, cylindricus; Altolamprologus calvus, compressiceps; Julidochromis marlieri or regani.
There is, however, a bit of a secret to making this work. Any other tankmates must be much larger then the brichardi to begin with, and they must establish their territory in the aquarium first. Purchasing an adult pair of calvus and juvenile brichardi would be an example of a situation that would normally work out. There is one important caveat: in a tank of less then 120cm (48") you would be limited to two pairs of fish when including brichardi in the mix.
