Agree with the others.
Just goes to show most LFSs don't know their arse from a hole in the ground.
below a male "location Chairel" I had just starting spawning colors
so wait.....the ones I have only have tiny little spots - I was under the impression the PEARL-SCALED name came from the tiny little white pearl-looking marks.....
is this completely ass-backwards? I don't get it. All this time I thought I had carpintis, but I really have TRUE TEXAS???
Yes that's true Frank, larger spots are usually carpintus.
Although for years both species have been interbred in aquariums (mostly because people didn't realize the difference between the half dozen or so species of Herichthys (much like what happened to Paratilapia)) so there is an aquarium strain that pervades LFSs, or chain stores, those stores that don't order from trusted people Rapps, or Gage, etc I find to be suspect.
I've been in LFSs that can't tell the difference between a fire mouth and a JD, so telling Herichthys apart would be a gargantuan leap for most.
And when young is very hard to tell them apart.
Above a young H tamasopoensus
below carpintus "Chairel"
or even telling a species apart when in different stages of life can be interesting
male carpintus one day
same male another day
I've also seen that the Cyanaguttatus pearling is more uniform in pattern. Carpinte pearling is not as evenly lined up across the body. That might be due to the size of the pearls...but there you go.
