If my knowledge is not wrong, sunkist is the one that needs brackish water to breed or for the eggs to hatch.
Orange cherry is different from sunkist.
I have had orange cherries before, but their breeding rate seems slower than the other cherries. Red and orange offsprings may still have some of the colors or will go back to their wild colors.
I only had luck with dark blue cherry and dark brown Sakura, some offspring turned out wild, some had nice dark colors.
