I have fry from a blue gene/gold gene pair of JDs.They are almost 2 weeks old now.My question is,do the ebjds need to be separated from the regular jds?There are also some gold jds mixed in too.Do all the jds need to be separated from each other?If so at what age does this need to be done by?I was told when I got this pair that they will produce ebjds,gold jds,blue gold jds and regular jds.
