DP-Yes there's blue on it. It's a female. She is in my 75 and that's her male with her. The second picture also in my 75 and their a pair.
Funny thing is that the last two pictures are the ones in my 55 gallon and all three have blue on them two,I just cant seem to catch it with my camera phone. The third picture are also a pair. So far I have only been fortunate to keep eight babies alive(knock wood). They're two months old. They are in a ten gallon and I will try to get some pictures soon.
