There is also the Lahillas to round off the main 4 that are in the hobby. There is also many more location based carpintis as talked about in this thread http://www.monsterfishkeepers.com/forums/showthread.php?278431-6-varieties-of-Herichthys-Carpintis. But thats a topic in itself.Herichthys cyanoguttatus, are your regular Texas...
Herichthys carpintis is the other...theres 3 known variants so far...Chairel, Escondido, and Vontehillo.
And then theres the man-made Red Texas.
To me they are all beautiful, even the regular Texas. Some people value too much what is "Sexy" and will throw around whats new and hot. Don't mind the kids
