the goal here is a texas cichlid that is red basically. some SRT's nowadays are taking a flowerhorn shape. these IMO are not SRT's, they are a flowerhorn with red texas colors.
red fish (preferably a fader) + texas (cyan or carp) = red texas
a faded red texas regardless of linage = SRT (super red texas)
the quality on these have gone up in more recent years due to the linebreeding.
