Have I got a Green terror or blue acara ?

  • We are currently upgrading MFK. thanks! -neo
I will put a video on YouTube up of it.
 
Everything about that fish says GT to me
 
Looks like a GT new in that tank with bigger, more established fish and not settled yet. No (dark) background in the tank could also be a reason for lack of color.

After the one day of having this fish I have noticed that it's not as aggressive as people say it is.
what I've noticed is if the other fish in the aquarium try to attack it then the fish fish defend its ground.
Typical of tank bred green terrors, especially when smaller. Usually not as bad as the name or reputation suggests. Of course, like many cichlid species, they're going to vary by individual, behavior when brand new in the tank can change once they're more settled, behavior at a small size isn't adult behavior, and if you crowd them into too small a tank, have a breeding pair, or another fish thinks he can mess with it all bets are off. But, a lot of them are like you describe, not looking for trouble but don't intimidate easily. In some tanks they'll work as a police fish, breaking up trouble rather than causing it.

None of this means you can't get a mean one. Now wild GTs-- whole other thing. They deserve the name from my experience with them.
 
Andinoacara Rivualtus. The are an awesome species enjoy!
 
What would you suggest I should do to help bring out the colours? Also can the fishes cour turn to black?

Just leave it alone. Once it feels comfortable in its new environment, its color will come out. Plus, color will also intensifies with maturation. Black coloration is a sign of stress. Try keeping the tank's light off for a little while.

Can these fish getting along with Blue Acaras ?
There's a reason they are dubbed "terror", so more likely than not, the answer is, no.

Has the color come out better?
