Keep an eye on it. An angry male green terror can make short work of any fish it wants, and will easily claim a 75 to itself.

Looks male to me. The female Rivulatus are more streamlined and have a darker, almost olive green sheen.
I can't think of a big Tetra that a full grown Rivulatus won't eventually eat.
My best male Rivulatus ate an entire group of adult Buenos Aires Tetras. The BA Tetras had been long time tankmates with the GT. When he reached nine inches the blood bath began.
For schooling fish tankmates, look at XL Barbs, maybe Denison or a Dawkinsia variety.

Why there is no sign of hump.When i can expect that
Humps don't always show. It's a complex combination of genes, dominance of tank, breeding etc that determine if and size of humps.

My male Saggitae keeps a slight mound

But when he was courting three new females I got him, his knot expanded

So basically it's a waiting game till/if he grows one and size.

I had a wild male for time. When I got him he had a knot going for his size. It went away after coming home, no females to court and no male competition.

In my aquarium a blood parrot is Alfa of the tank.And there is no female green terror so there is very few chance i think.
 
Yes a female blood parrot but she has spawned many times with male parrot
 
If you have other more alpha cichlids in the tank, it may never develop a nuchal hump.
These humps are liquid and fat filled cavities that appear and disappear as signs of dominance, and react to hierarchy in the tank.
I keep my Andinoacara with Roeboides tetras, similar in size to the cichlids, and they are never bothered.
To me, the best tetras to keep with Andinoacara would be those larger varieties from west of the Andes
 
Does it affect colour of the fish also because that green terror changes colour in every few minutes.Sometime it is very bright good looking and few minutes later it looks looks dull with white lines on his body.
