i'd say they are both neat fish, but the Armatus is probably your better choice because it will be able to keep pace, growth wise, with peacock bass.... tigerfish grow much more slowly, and unless the tiger is much larger than the peacocks in the beginning, which could be a problem for the peacocks, they will eventually outgrow him and possibly eat him.... Armatus grow quickly, like the bass .... when keeping tigerfish they have to be the fish you center the whole tank around because of their slow growth, and unique behavior.... they need lots of current and open space cause they are such explosively powerful swimmers, and when spooked they will smash into things very hard and cause major damage to themselves ... i tried peacocks 2 times, first time i came home to a GATF's tail sticking out of a peacocks mouth, so i got rid of the bass, then tried another smaller one, and within 3 months he was too "cichlid" like as far as aggression and chasing, and when feeding would scare everyone away with his aggression and eat all the food, thus growing faster.... i got rid of him before he ate anyone.... I had a Nile Perch, he was much more passive, and had a great personality, and grew a little slower, but non the less he grew too fast, and was becoming a threat to my ATF's as far as being able to eat them.... those perch/bass like fish have such huge mouths they will try and eat anything eventually.... i may do another Nile perch though, now that my tigers are 10-12 inches minimum, i really like them
