BYC member "Halo" raises LF Blue/Black Rocks.....I would suggest contacting her to see if she has any eggs for sale. She is located in Fla somewhereAny idea what composes/how one makes/how one avoids a birchen?
You will need a start from "pure" stock in order to have Blue Rocks. Keep in mind that the "blue" color does NOT breed true (i.e., Blue mated to Blue does not yield all blue offspring)....you will get combinations of Blue, Black and Splash depending upon the matings you set up
Hope that helps
