Hi There! I have a full grown male Trimac alone in a 75 gallon. He has no real Nuchal Hump and was wondering if there was any tips to help it grow or is it just some fish get it and some do not?
Trimac Nuchal Hump

A Nuchal Hump is generally a show of dominance/ used to display to females a fish high in the hierarchy.
When I kept a pair of Amphilophus Citrinellus, when they were about to spawn / going through prespawning the males Nuchal hump would dramatically increase in size, but after the spawn the Nuchal hump would significantly decrease in size.
In a community of males generally the dominate male/ males higher up in the hierarchy would display a Nuchal hump.
My Amphilophus Saggitae was the same, during breeding it would pop out
Now that he's alone he just keeps a slight knot

trimacs don't naturally get that big of a noticeable nuchal hump until/unless they really get big and beefy. don't worry too much.
Honestly the closest thing to a 'Nuchal hump' Ive seen in a true trimac is
