In my collections,there are 1 male pastels and 3 females of pastels,sure i wanna noe about them,coz they came from Opaque Vs Platinum ; so what is pastels?i took a phrase from to solve the question ;

Pastels are iridescent bettas (blue, steel blue and green). It is the (C) cambodian or non-red gene that differentiates them from the regular dark body iridescent bettas. Pastels are homozygous for cambodian, which gives them the light flesh coloured body. Most Pastels also carry a little opaque factor to give the iridescent appear more solid. Without the opaque factor, the iridescent color would be translucent in the absence of dark pigment (black or red)
