It's undoubtedly a male, a Really good-looking one too!
 
Hi SaltyPlum SaltyPlum ,
I agree with Deadeye Deadeye and FuriousFish FuriousFish . Your GT definetly looks male. He has a very steep forehead with a nuchal hump. He also has a pretty prominate blue "beard" also. He's a big ole chunky dude too. Your GT looks great.

I'm pretty sure it is a female. Walked past the tank and notice it has claimed one corner chasing all other fish away, which is random behaviour as it's normally pretty placid, and I'm pretty sure that's an egg tube sticking out?

It keeps running its thing on that rock but nothing coming out. When I try and get a closer look it attacks me from the glass ?

it looks like a really chunky female. The clear fins and blue bearding on the gill plate are a dead giveaway. Especially the tube is definitely female-shaped. A male fish's are sharp and small. It's very colorful for a female.

The breeding tube speaks volume. So to reiterate so far,

The blue bearding increases chance for a female rivulatus (not all females have this), the lack of reticulated pattern in the dorsal, tail, and anal fin points to a female, and the nubby breeding tube points to a female rivulatus.

So, intense body coloring and hump don't necessarily point to a male because this female is showing dominance over the other fish..

I agree with Rocksor. The blue bearding and the darker colours are a giveaway for me and then you have the breeding tube which confirms it. I have seen dominant female rivulatus portray characteristics of what we typically see in male species such as a nuchal and thick orange band in the tail fin. She is displaying these characteristics due to the absence of a dominant male which tends to happen quite frequently when females are kept separated from males.

what other fish are you keeping with her?
