Dude I cant vote cause I dont agree with any of the lineups. 1st off, strictly SA/CA fish, cuz thats how I roll. Esp bail on that ARTC, look what a bastard fish it is, eating on the other fishes fins (that poor con). A few payara,(if thats your thing right now) some asstd viejas, 3+ prochilodus, a fat royal plec,maybe a festae, and of course a big *** pike cichlid (you knew that was comin) like a cincta, marmorata, strigatta, hell any type of lugubris pike or crenicichla vittata ( I got this fat sveni right now......hint hint). Fill in any gaps as you like, with new world fish that is.
Just my 2 cents.
or a strictly parachromis setup like ruckfules has. The choice is yours.
