In any cichlid spawn, there can be a few exotic color morphs.
This is natures way of providing the species a way of survival in case the geography dramatically changes.
If some natural event happens that wipes aquatic plants, or the cover of terrestrial plants such as trees, one or two of the light color individuals could carry on the species, whereas dark individuals might no longer blend in and become easy prey for birds or other preatores.
Take these 3 carpintus in the shot below, they are perfectly camouflaged for their natural habitat.
But if some natural event that changed the geography occured, like an earthquake, a storm that wiped out flora, they might become obvious, and one of those alternate colored individuals may be the one that survives and saves the species.
I had a constantly spawning pair of managuense decades ago, and in each spawn there were always a few gold, non spotted individual, and also a few very dark ones.
There is a study I posted a while back that after a dam was built in S America,where even the skeletal structure of the cichlids above the dam changed within a short period to match the chang in habitat.

Some changes are obvious in rivers where the terrain is slightly different, take the Chuco intermedia below
Each are the same species, but from different rivers, not that far a distance from each other.
Natural selection always seems to favor, and change with the need of the species to survive.
