Help sexing a Urophthalmus

[VRWC]

Can anyone give tips on sexing a Uro? Its 8.5 inches and mean as sin.

Ive looked all over online and in all the other forums and cant find any legitimate answers on how to tell.

Thanks!

sorry, I meant to say tips on sexing it without venting...just based on physical characteristics or anything of the sort. I dont have access to the fish so I cant vent and the person with it cant either and wont take it out and take pics of the vent.

My only guess would be "maybe" look for black/dark dorsal? since both male and females look the same.


Too bad I don't have anymore pictures of pair I used to have.
