Females Fighting

[jerms55555]

Is it normal for females to fight outside of a cave? Or are thes two males...I think there females....but who knows.....and do females park themselves in caves as well? I thought two of them were females and I see them in the caves right near the edge...almst sideways most of the time....Just like this picture in this aquabid post....I have the same exact caves as well...maybe because it was the same breeder i bought mine from..

One more question....Do you think that zebra is a female or male?? The ones im refering too looks just like that one...which I believe is a female...Am I right??
