In my experience I have NOT found this to be the case. I've kept large groups (10+) of yellow labs with moderate sized groups (6+) of red zebras for years. The only interaction I've seen is my male red zebra busting up fights between two male rival yellow labs (the alpha male red zebra doesn't like to witness any fighting he isn't involved in). A red zebra wouldn't be more prone to breed out of its species than a cobalt blue zebra....skip on yellow labs or red zebras and get something else, yellow labs and estherae's would have a high chance of interbreeding even with enough females for each male (all mbuna/mouthbrooder could interbreed, but those two species have the highest chances reported in aquaria)....
Socolofi's are monomorphic, perhaps you're thinking of a different species?...Besides, the Pseudotropheus Socolofi are dimorphic, so males are different than females, and I want variety in my tank.
Darn it.:wall: I meant Pseudotropheus Saulosi.Socolofi's are monomorphic, perhaps you're thinking of a different species?
I'd say this combo is workable especially if a verified 1m/3f gender ratio is in place, though I like Coler's suggestions.How's this? 4 Labidochromis Caereulus, 4 Pseudotropheus Socolofi, 4 Pseudotropheus Saulosi, and 4 Metriaclima Estherae.
