55 gallon hap/peacock tank?

[rrcoolj]

So I want to do a apecies tank with preferably a type of Hap but im willing to do peacocks if I can't do haps. I've been researching online and there are three species of haps I have narrowed it down too which are Sciaenochromis fryeri , Copadichromis borleyi, and Copadichromis azureus. If I can get any of these haps what ratios should i aim for?, what diet should I feed them?, what growth rate should I expect?, and could I possibly put two males in one tank?

If I can't put haps in this tank I have two species of peacocks I am considering which are Aulonocara maulana and Aulonocara stuartgranti "Ngara Flametail". Again what ratios should I aim for?, what diet should I feed them?, what growth can I expect?, and could I possibly put two males in one tank?

With each species have 1 male to 2 to 3 females of each and keep temp about 78 or 80, plenty of hiding and use a mix of sand and gravel mix substrate, and as long as you feed a good mix of flake everyday and blood worms, krill, brine shrimp every other or just 2 times a week, growth should be no problem.

You don't think the haps will outgrow the tank?
