Just a heads up...
At maturity, argentea (especially males) are loners, and prefer a non-community life sttle.
At just over 5¨a maturing male I had, started killing all orher cichlids in a 6 ft tank, until I removoved it to its own tank.
He killed a half dozen other cichlids, overnight.
Another time when I kept them, only a mated pair coxisted in a 6 ft tank once mature, no over cichlids were allowed to live.
Once they spawned, the male also killed the female
One of my favorite Central American cichlids, but require a large territory just to themselves.
