Knew they were girls, Bob is comfortable with her appearance
. Societal pressures can be soooo demanding
.
Bob is an alpha female. She bogarts all the goodies which is actually one of the reasons Ducky is so small. Ducky, oddly enough can't stand to be far from Bob though. She's even got her own rock to sit on but its never good enough unless Bob is there as well.
I remember once hearing squabling coming from the tank and picking Ducky up to see what was wrong only to find Bob attached...by hanging onto Ducky's foot with her mouth.
Ahh my two prima donnas....
