I have two german blue rams that i believe to be a male and female from personal id'ing and getting opinions form other hobbyists. But I have a problem with this. My supposed female is bigger than the supposed male. She has the pinkish purplish belly and is a beautiful goldish color and shines gold with light. She has the black spot that looks dark but is not completely black. It has minimal blue spots. Then I have my male ram who doesnt have huge second and third rays in the front like some males but they do look bigger than the other fins on the top fin(sorry forgot name.) He doesnt have a pink belly but doesn't have a solid black spot. When he is feeding or feels teritorial, it gets solid black otherwise it is almost missing. It is very faint. He is very blue compared to the other one's strong gold color. And he shines a nice blue shade as well. Since I had them, they have been getting along fine. I had them for about two months. Recently, in the past two weeks and still going on now, the supposed female chases the male away from certain spots. If he goes near a rock on the right side of the tank he gets chases back to the otherside. Or sometimes he just gets chased for no reason. She will peck at him but doesnt seem to hurt him. I mean they have been living together for a while now and i bought them from the same tank. Tell me what you think but while you do i will try to get some photos i have of them.
