Sexing u. fimbriatus

[Momokat14]

Hey all! Super new to this forum (and pretty much all forums) so please bare with me. I bought a 1.1 pair of u.fimbriatus and need help verifying that they are 1.1. I have joins groups and read online but there is very little I can find that shows and tells how to properly tell sex. If anyone can help me out or point me in the right direction it would be amazing thanks

hey Momokat14, perhaps upload photos so that we can take a look at them and try to help you sex them? A picture of the underside of the base of the tail would be best, e.g. taken through the glass of their tank.
