Depends on what you are calling a real RT? For some time people have been breeding texas with any of the following - blood parrot, KKP, red devil and fader flower horns and calling the F1 progeny red texas on sale. Some fade, some don't and the fade may be complete or incomplete with a orange-red, pink or yellowish base. Many F1's are nice display fish in their own right but the males are usually infertile as are some females - probably less so where the texas is hybridised with a pearled fader flower horn with some texas parentage. The F2's are another kettle of fish (haha), where the female F1 of any of the above is mated with a male fader or other pearled flower horn with a good red colour base - then you start to get some really nice fish and male fertility and can start sibling inbreeding and establish some consistency in the appearance of the offspring.
