You´d have better odds getting a number of obvious females (as many as you can find or afford) and allowing it to have a choice.
My preference would be atleast 3, (the more the better). They can be 1/3 smaller.
My experiance with the genus Andinoacara has been with A coeruleopunctatus, where I started out with a dozen juvies.
A maturity the largest (alpha) male killed all othet males, and a few females, allowing himself and 3 receptive females to live peacably in a 6 ft 180 gal tank.
The male would move from female to male spawning with each, seasonally.

Female with fry a few months ago above male below, same approx time below

They have been spawning this way for a number of years

Sometimes they will end up to be multiple spawns in the same tank, and fry predate on each other.,
