Went into petco recently to buy some tanks for my cyano fry and bristlenose plecos and ran across this fish in a tank only one like it managed to buy it for $5 as a jack dempsey? . There fish were all mixed up , im thinking carpintis just based on the looks looked similar to my true texas but markings are different. Started looking at my escondido juveniles and noticed look almost identical but this one hasn't gotten color yet. Hoping someone here could help me figure out what it could be .
Thanks in advance for the help , been slacking on my threads have set up a pool pond and much more since last I was on here been staying busy

Duanes I'm thinking your right on that by how it looks , I just got up to go turn all the lights on for the tanks and pond and it's looking more like the tamasopoensus so far. Pretty interested to find out for sure once it's settled in & gets colored up a bit more. I noticed it's got the black dots but seems like dark bars on it are showing now started fading back out alot since light came on tho.

Funny, I once bought a small Texas as a jd!
Just to compare, this was my jd at 0.5 inches:

A lot less spotty than the juvie herichthys.

First pic I thought hericrhys cyanogutatum last pic looks like a Dempsey fry.

and now I reread it all and standby what I said but maybe it grows into carpintis too- hard to tell if it’s speckled/ vermiculate or if it’s just spotty. hahaha

Deadeye that's awesome that's usually only time I get fish from big stores now curiosity got to me I guess I've actually been wanting to get me some jd's too but have cyano pair and 12 fry I kept to grow a bit , couple green sunfish hybrids , green sunfish, coppernose bluegills 3 carpintis escondido juvies( started with 9 but these things were crazier than my true texas started picking each other off at a very small size) , central longears, pumpkinseeds & a couple warmouth . Got to get my actual long term pond built or tanks up first tho just got a cheap basic pool pond atm going to do woodframe & epdm liner pond or fiberglass tanks. Duanes I was thinking those were pretty rare I was leaning toward carpintis at first and that was why but it was so stressed out up there hard for me to tell right now

A little interesting trivia about either Herichthys species, is that the area they come from in Mexico, is seasonal.
Water temps may reach 82'F in summer, but drop to 65"F in winter.
And as adults the spots on tamasopoensis become more yellow, whereas carpintus more blue.
And the area tamasopoensis inhabit and prefer is usually near waterfalls, or areas with high flow, so they may require more oxygenated water movement to thrive (also provided in cooler water).
I didn't use heaters in tanks with either species, and in winter water temps dropped into the 60s, with no ill effects
