blue acaras get more than 6". i saw one for sale at my lfs that was at least 9" (and it wasn't a green terror) it was labled as 'XXXL blue acara'
i had one that i grew from about half an inch to 4 ish inches until it died in a ich epidemic (3 day power outage, temp down to 17 celcius and clown loaches are not a good combo) i was really sad because it was and still is my favourite fish ive ever had. i wan't to get another one, but i have nowhere to put it because the tank it was in is now a mbuna tank, and the rest are full. i fed it bloodworms and regular tropical flakes, and im pretty sure it ate about 20 neon tetras over about a year. great fish.
