Acara or Green Terror

I am relatively new to the hobby and am learning a lot in a short period of time but I am puzzled by two of my fish. Both were sold to me as Blue Acaras. They were very small at the time of purchase so they looked like Acaras to me, but as they have grown I am thinking they are Green Terrors. Can someone please identify the species of both and the sex as well. I have gone back and forth about 750 times on this one ! Any help would be appreciated.

Any idea on the sex of each ?

Just seen this thread - what did you end up doing with the terrors? I really really want once but only have a 145 litre tank and so am after an acara. If you kept the terrors, how big have they got?
