can you share any information on the Dark Knight Rams? I've not seen this cultivar previously.... I'm googling and getting nothing... ok... never mind.. found plenty.
Around 2014 a breeder in Israel named Mishmar Hashiva started working with Rams that were a bit darker.. He worked in cooperation with the Discus breeder Danziger Discus Farm in Tel Aviv. Eventually, through selective breeding, he's obtained viable healthy true breeding fish. These are now referred to as
Black Rams. However, they still retain some of the wild coloring in the body.
Later, a breeder in Praetoria, South Africa, Marco Du Toit (did work with Powder Blue Rams and Pearlmut Rams), began working with especially dark specimens that he received from Israel, and after about a year and half obtained purely dark, healthy
homozygoes. Further selective breeding resulted in obtaining specimens that were healthier. These he named Dark Knight Rams.
These have been on the scene for about a year now.
Color forms from these selective breeding programs are fascinating:
German Blue Ram (I'm told after generations, these will always revert back to the wild form... don't know about the others below)
Gold (xanthistic) Ram
Powder Blue Ram
Electric Blue Ram
Pearlmut Ram
Black Ram
Dark Knight Ram
Then of course there are the shapes, Balloon and Long Fin varieties as well (neither of which I care for).
