I´ve bred an Surf City male to a St. Matthews female,
although the habitats, where their mothers were caught are not in far distant, they have conspicuous different patterns and colours.
This is what they´ve produced together:

A lot of the siblings of their parents discovered only very few redish colour
or no at all, but most of these showing up first red after only 3 month and I´m expecting them all to shed again soon.
They have redoubled size and weight yet and remain exceeding feeders
