Dual Breeding in a 75g?

[___James___]

I’ve got 8 Aulonocara Baenschi in my 75g (1m 7f) and was wondering if I could fit another group in there. I’m working with an fx4. Is there any small haps that could fit in here or should I stick with just my current group? Thanks

Maybe a smaller group of placidochromis electra or tetrastigma.

Maybe a colony of Haplochromis Sauvagei / Yellow Rock Kribensis. I have a few of those feisty little guys. Very colorful, tough & compact. Can easily be kept with Aulonocara.
