i agree, not that i wouldn't keep an aro in a 180 (6x2x2) or even 150 (5x2x2) and a lot of people do keep aros in 180s, but to be really fair to the fish you should at the very least give it a width of the fish's maximum lengthrottbo said:full grown healthy aro can reach almost 48" so they would need a 10' x 4' footprint minimum
ateasst IMO
