Carpinitis x blood parrot hybrid or a purposely bred short body carpintis.
I've always been confused by the different types of Texas. duanes is this an H carpintus or maybe a hybrid?

I had him about 5 years ago but sold him due to business crashing when we had some big political problems and I had to downsize. And just like yours Viktor he was one mean and territorial SOB, he eventually had to go solo.
Anyway just for fun try putting some blue-ish light on that tank buddy, then watch your Texas instantly turn into the most stunning fish in the tank, those micro pearls would really pop.
