Help sexing my Zonatus

[LIGNARI]

Here are pics of my Zonatus.
He/She is about 6".

Male or female...what do you guys think???

Cant tell from those pics. I could not tell with my male till he started breeding
with my female Bifa. I figured he was male when he started developing his nuchal and dropped his tube.

Here is my male if it helps. Male will have slim tube angled back, female will
have fat tube slightly curved down. See pic 3 not very good but can clearly
see the vent tube.

Woh never seen a yellow zonatus before. Looks kinda bifasciatus there. Nice fish

The yellow one is a bifa.

Don Conkel told me that female zonatus have a metallic dorsal fin while males don't. Here's my old female for comparison.

Hi,
I've just sold my breeding pair of these.To be honest you cant sex them until they breed. what I had considered the the male by virtue of being bigger and better coloured turned out to be the female

you can see her laying feeder eggs in this vid.

Modest_ were you the one with the really mean zonatus? I remember someone talking about their zonatus terrorizing their tank.

Yeah, she was the single most relentless fish I've ever owned. Pick one out of the crowd and harass it to death, then start the process over.

The male seems to have more red on the dorsal and caudal fin.

Thanks for your replies.

I'll be loaning it to a friend who has has several of these.

Hopefully, it will pair off with another and I'll definitely find out male/female when it starts breeding.
