Male or female convict ?

[Matthew English]

Brought a small convict today from aquatics, was being attacked by another, have a look at its back fins, so i rescued it,
I was wondering can you tell if it's male or female by the picture

 

[Reiner]

Don't see any orange scales on the belly region in the pic so I would say male

 

[Gourami Swami]

Looks male to me as well
