Yes,I agree with sinister.1 pair,perferably a breeding pair ( so they would show as much aggression).Maybe some ottos would work well also,Not quite sure how many more fish I would add to this tank it is only 10 gals.I was planning a similar set up, a 10 gal.with plants and dwarf cichlids(1pair) a couple ottos and maybe a couple of shrimp.Post pics when you finnish,That would be shweeeeet.
