Zebra1/4 are the biggest.
Also check out ZEBRA1 Top view.. it has a Heart Pattern
Zebra1 I think its a Female (its the biggest Zebra I have)


Zebra2 I thought it was female due to Fin curves but closer look and venting points to Male.



Zebra3 I have least confidence with (leaning more towards Male)



Zebra4 IS A FEMALE. IT HAS TOO BE!



Opinions will be much appreciated (please make sure you state which Zebra your commenting)
Thanks
