we have yellows 1x male and 3x females you should probably stick with 1x male per group of females we have had 2x males in the past and didnt end up so good :oops:
so anyway we have a 700 litre tank with electric yellows - electric blues -venustus giraffes - boreyli - livingstonii's - auratus - red empress - ob marble aulonocara's
they all get along just dont mix other species aulonocara's in the same tank generally one male of one species per tank and you'l be right
we have a range of fry sized from 1-4 cm in electric blue - electric yellows -aulonocara baenschi - dogtooth afra's - red empress if your interesting in growing them up
