SRT 's are found in various colors...Red, Orange, Pink, and sometimes yellow.
SRT's are fish that have faded from a "Traditionally" looking Green/Blue texas, to either one othose colors.
Red color is the most favorite and most pricey type of SRT. Orange is the next, and so , and so on.
I believe this was discussed in a previous thread.
So bottom bottom line, a "traditional" looking Red Texas (that looks like regular tex), that Fades and shows color (Red, Orange, Pink, etc) is considered to be SRT. With the red color being the most sought after and expensive of the strins of SRT. The color it fades to, contibutes the grade(quality) of fish. BTW, Red SRT sometimes lighten up to look orange when Breeding.
Just my 2 cents!!!!!!
