Being it is from petsmart and the chain sells red texas made from texas x flowerhorn matings my guess is one of these hybrids that leans towards looking like green texas. It is just like the many sold as red texas that favor or look more like flowerhorn. In any given first generation cross some look like one parent and some look like the other parent with a few looking somewhere between both parents. Also knowing the supplier of petsmart one can look on their list and see if they even offer pure green texas right now or just the red texas. I did look and they do not list Herichthys carpintis but do list both red texas and Herichthys cyanoguttatus.
