Hey

Just took out 3 zebs from my colony that I am thinking are males. Please take a look below and help me confirm? THANKS!!

Zeb #1:




Zeb #2:




vent of #2:


Zeb #3:



vent of #3:


Thank you for your time!!

turn them over and check near the genitle area if they have a v shape its a male if they have a u shape its a female

The only way I know to sex them with any degree of certainty is to vent them as suggested above. Its usually most effective to get a pic or check right after a water change or else to catch the fish and remove it to a clear container with fresh water.

At what size does the vent show gender dimorphism?

Ill work on getting some good pics.

Thanks guys

Hey Louis,

My first forum post is to help you out and add some info to your discussion.

Not sure if you've seen this yet but I'll probably subscribe to this thread for future reference.

Here's a nice link with pictures of male and female vent / ventral area. http://www.plecoplanet.com/forum/showthread.php?t=10056

http://www.mchportal.com/fishkeeping-ma ... a-l46.html check this article from a breeder i bought mine from very good and the genitles are there almost from birth you can see them

Thanks guys, I just vented #2 and #3 (since I am 100% sure #1 is a male). To me, both look like males. Correct?

Thanks

i would say they are all males looking at your pics

Cool, thanks

2 looks like a fm to me. below is a pic of a fm Hypan. L173b from glasser. Note the similarity between zebra #2 and my pic in terms of the venting.

Thanks TTA, I guess time will tell.
