Pretty sure there is no fish called red slayer. Not trying to be rude or offend anyone, But if you google red slayer cichlid it takes you to a thread where some idiot is trying to say that he breeds "red carpintis" and that they are different from SRT and that they are related to their ancestors lol. He says that SRT are flowerhorn and that these are not FH. If you look at the picture you can clearly see it is a SRT. He says he gets his red carpintis from breeding with a red slayer cichlid which is most obviously a blood parrot. SRT or red carpintis are all the same. It is either a carpintis with a blood parrot-most common, or a cyano texas with a BP or red devil. I have heard of successfull attemps with Red Devils as well but for the most part it is almost always Carpintis X BP. They are not flowerhorn. By the way great looking fish. Love your texas and it's offspring. Hopefully you can get some good looking fish for line breeding. I would say that the offspring you showed here is a great choice to rebreed with the parents. Good luck man.
