Your new Andinoacara is much younger, so comparing body shape to your previous adult, is not realistic.
At a young age, all Andinoacara are hard to tell apart, and there are at least 8 described species in the genus.
It does (however) look GT to me. but then again, the common name GT is applied to at least 2 or more of the genus, interchangeably.
I've heard aquarists argue, ad nausium, over what is what.
So only the scientific usage, is of any relevance to me.
The one caveat, is that there is a lot of cross breeding between, A pulcher, rivulatus and stalsbergi these days, which is mutting up the market for legitimate species.
So it is possible it is one of those intentionally disrespectful crosses, or unintentional hybrids from out of ignorance, is also possible..
But showing the same body shape, and true coloration of your previous one, ....is months,..... if not a year down the road.
I keep Andinoacara coerleopunctatus, and the only reason I know it is a true representative of the species, is because I caught it myself in its home range, Panama.
If I saw it as juvie in a LFS, there'd be "no" way to know for sure these days, mutt or not.

my old green terror who sadly died but looking at both together not sure if it's a terror at all would appreciate any feed back
guess only time will tell.
