Sexing Whiptail Catfish - Sturisoma Aureum
#1
Hi All,
We purchased a pair of Whiptails over the weekend and after a long time in the shop trying to get a pair we took two we thought were male and female to see how we get on. Now they’re settled on the table we’re trying to decide for definite whether we were successful, or whether we should swap one. I’ve attached some pictures of them individually to aid sexing. 
Any help would be much appreciated!

Hello and welcome to the site. I’m a newbie so sorry can’t offer any help. Hopefully one of the others will be along soon. They are smart looking fish. Think one of our lady members also has these fish ?
Enjoy the forum

Hi and welcome. Those are beautiful looking fish I personally think that they may be too young to say for sure. I have two red lizard whiptails which I have now had for a year. When we got them they were maybe about two inches long, they have grown a lot since then but it was only after us owning them about 8-9 months and them growing another  inch or so that we think we have two females.
Have you checked out planet catfish? Pop the whiptails full name in and quite a few photo's come up which might help with the ID. (Sorry I'm a computer dinasaur and don't know how to add a link!)

I wasn't on yesterday PM, sorry.... Tongue
Ian has the pic for odontotes, the pics of the bellies are too dark and unfocused to be able to see if there's a difference in the "vents".
They are very difficult to sex, especially when young.
Yours are very nice specimens. Smile
If at first you don't succeed....

Enjoy your fish, shrimps and snails!

Thanks for all the replies guys!
@Sarah ours are around ____ long at the moment and one of the others in the show had some bristles on the cheeks (all the same size) but these unfortunately disappeared as soon as we started catching and agitated them.
@wingnut55 Do you know what size you'd expect to see the odontotes? The one in the picture you posted looked much larger than ours, but I could be getting the wrong sense of scale!
@plankton What differences would we be looking for in the vents? I'll happily stare at them for days in an attempt to notice! Smile And can try to get some better belly pics too!
Rob

The females' vents are more rounded and bigger, but there's not much in it. Wink
