It looks like she wants Rocko to climb aboard. He's obviously not taking the hint.

She wants to mate. Looks like someone is hormonal.

Thats what someone else told me too

Now I know I have a female

The big question is whether you have just one female or if you have two. Rocko didn't seem interested in the display at all.

Rocko is definitely Male all signs and his body colour says Male.He's not gonna seem interested right away he probably doesn't understand what she was doing.

You can't visually sex a pied so his body color doesn't tell you anything.

I mean because females keep their pearls and his behaviour too and his flock call its just Male and I can just tell he is a Male.I could tell Loki was female just by looking at her and I was right and I feel the same about Rocko.
