Escondido is a location variant in Mexico,(not in Texas), and Electric Blue is simply a "selling point Trade name" for carpintus, neither are endemic to Texas, so the Texas moniker is an oxymoron.
Not realizing carpintus and cyanoguttatus are separate species, unwittingly perpetuates hybridizing, producing indiscernible mutts, that for serious cichlids breeders may be problematic.
I have seen many of those confusing unidentifiable mutt ID threads appear here on MFK
Some aquarists are serious enough to keep location variants like Escondido, or Chairel, in separate tanks, to not contaminate the variants.
The carpintus in my photos are location variant "Lago Chairel", near Tampico Mexico, it is quite near the sea, and so close, that the lake is often inundated with significant amounts of sea water, so much so, it becomes brackish.
Seasonal winds also often create cool water conditions., I would keep them in unheated tanks, where water temps easily fell into the low to mid 60sF.
I also kept them in outside tanks in summer thru fall, which seemed to intensify colors.
