Hi all! Choosing the right CA/SA cichlid

[luckyboy]

Hi everyone! I am a new MFK member and I am starting to enjoy this site a lot. I have learned some much these past few days by reading some threads and articles, it is very ressourceful.

I will have my future tank soon, it is 110" long x 33" high x 36" wide = 565 gal + 90 gal sump.

I am searching for an interesting and not too common group of CA/SA cichlid that can live peacefully with an silver arowana and maybe a few stingrays. I were thinking a group of RTM. I will appreciate if someone can help me for it.

Thank you

How about a group of cichla

 

[Aromantis]

Do they all have to be the same species? Because if not I would recommend a mix of vieja, paratheraps, herichthys, amphilophus, and parachromis. I realize that that doesn't narrow it down very much at all but it should help a tad.
