The groups imported are heavily male. But even then, females are very tricky to identify. They will have some facial spotting and lines just like males, until they turn on their spawning colors when the face turns dark jade green and the spots disappear.

This is hard to explain but females can “turn off” their facial markings. Sometimes they look very faint and seem to blend into the background color, much the way discus and angels can “invert” their vertical barring so that its color goes light. Males cannot do this — they always have bold, dark spotting. I’ve also noticed in mine that males have very blue faces while females tend to have yellow/green faces like notatus.

RD, these are all formally described as Heros severus. They have red necks, 8.5 bars, and mottled green-yellow patterning that overlaps the vertical bars. Like other Heros species they’re spread through a fairly large distribution area (as opposed to a single river or lake like some species) and so there may be slight differences/geographical variants, but they’re all basically the same fish.

Sexy fish.
Is it just me or is the head profile a little different ? Maybe a little steeper ?

Looking good Jason, hope that you get a pair.

So Ryan, what would be the most accurate way to describe these in your opinion? It's probably going to get really confusing down the road if these are being collected in various locations.

With the rapid findings or different locales of Heros, they are just labeling them with the collection locale.

If they aren't known, the are just Heros and "sp. location"

If they are a color variant of an identified one they also add the locale. Such as Heros Severus "Curare"
 
Why would it be sp.location if we know its a heros ?
 
If a catch location is known they will include it because there can be slight variations in different locations even among the same species. For instance, something like Geophagus altifrons has a wide distribution. There may be slight differences in size or color among the different catch locations.
 
I always thought sp.location was a classification/identification of an unkown species but a known catch location
