Herichthys cyanoguttatus or carpintis

  • We are currently upgrading MFK. thanks! -neo
One of the traits that distinguish H cyanocuttatus (Texas cichid) from carpintus (not from Texas) is the naked (spotless) area around the nose of cyanoguttatus, shown in post #1.

But there are others in the genus from Central Mexico, that are not Texas cichlids either, just because they look simlar.

There are a few more in the genus that look similar, H minckleyi, H deppii, H tepehua, none are endemic to Texas.
 
Another example of confusion are the cichlids called Starry nights, from the genus Paratilapia, that have been randomly and mistakenly cross bred like the "Texas" clade above, creating mutts.
They look superficially similar, but on closer examination, there are are least 3 separate species, and maybe even more.

Thank you, sir! :)

I have been casually looking for H.cyanoguttatus for awhile now, hoping to find them locally as I don't order by mail. I have come across H.carpintis several times, at least that's how they were labelled, but have never been offered cyanoguttatus and didn't feel comfortable with my own ability to distinguish the two. This ^ information is much appreciated. :)

Does this hold true for smaller fish in the 1-inch range? The fish shown in post#1 looks fairly small, maybe 3 or 4 inches...?

Even at 1 " ,(at least to me anyway, tha carpintus are distinctive.

But then again the LFS caveat rears its ugly head......
With all the years of mistaken identities, random inbreeding, its going to be hard to tell, whos who, unless you go to a breeder who's legit, and kept cyanos separate from carpintus.
Or caught them in Texas (such as newworld in post #2).
Might it be time for a collecting trip to the Rio Grand?
