Nuchal humps are often temporary, resulting from dominance.
They are lipid and liquid filled sacks that can appear (fill) or disappear (shrink) with hierarchy status
Although in some cichlids, they are more common, some cichlids humps are absent altogether, as stated above.
In Amphilophus, Nandopsus (left below) and VIeja they are common, but vary in the M argentina with status, below right, or only slight in Parachromis (middle).
In shoaling type cichlids (like the Cribrheros below) , they are often minimal or only present when a pair breaks off to spawn.
Since there are almost 1,000 new world cichlid species, there are plenty non-nuchal sporters to choose from.
