its not and ebjd, and there is NO WAY TO TELL VISUALLY if a jack is BG or not, that simply means that they carry the RECESSIVE gene for the ebjd coloring, but they will not express this phenotypically (visually) there is now way to tell a regular jack from a bgjd unless you were specifically told it was a blue gene by the breeder or you can breed it with an ebjd and have some of the resulting fry be electric blues... Good looking fish though, def gonna be a stunner when he matures
