I have 5 Jacks in my tank right now. Two of the 5 are very dark and the other three are very light. The two dark ones seem to be buddy buddy with each other, and when one of the three come out of hiding the two darks ones run them back into hiding. Does this mean that maybe the two dark ones are my dominant pair? I only have room for two in my tank. Should I pull the three out now?? Thanks!!
