Sexing Green Terror

[btwaltz]

Hey guys,
I added a new green terror to my tank a couple days ago and am trying to determine the sex of it. Any ideas? Thanks! - Photo is attached

Also - I have a salvini in a separate tank; would it be ok to move it in with the new green terror? The salvini is around 2-2.5" and the GT is around 2". My concern is the salvini possibly bullying the GT. The tank is a 40gal

Thanks!

your salvini will most likely tear this guy apart. Salvini have to be with bigger fish. Your GT is to young to sex.

Green terror males will be quite bigger than the female when older with head nuchal hump and nicer colouring but agree its very hard when young look out for elongating fins which are a lot longer than females and females stay more rounder
