If you have in mind to keep these fish together you have to set up your tank partly heavily setted with rocks and the other half with lots of swimming space because Auloncara spp. do not use a lot the rockwork. If you have a high tank you have no problem ...
I keep mine with - Haplochromis burtoni ( breeding pair ), Labidochromis chisumulae, Pseudotropheus "red top Ndumbi" ( breeding pair ), Matraclima " blue red top" ( breeding pair ), Metriaclima estherae "red", Copadichromis borleyi "red fin" (trio), 4 huge Synodontis ..
I think you can safely keep those mbunas with them ... are those Pseudotropheus demasoni or a male Pseudotropheus saulosi ??
At first you are in control of your hobby but later on Fish Keeping will manilpulate you :s
