Please help sex a GBR!

[FishPie1]

Hi All,

I have a German blue ram for about a year, my hunch is it's a female but would love some help and to know your thoughts!

It's never had a pink bellow,

Thanks very much,
Martin

My guess would also be female. If you could see the breeding tube that would be more accurate.
