For the last week I've been debating trading away my jack for a green terror, and these green terror threads keep coming up. I keep seeing how amazing they are and every one of the owners commenting on how much of a finger-chasing glass-banging lively fish they are. They are exactly what I wanted for my "wet pet" that I thought my jack would be, but it looks like the GT may be my best bet because I don't have a tank big enough to house a texas/amphilophus/oscar.
