Yeah what Hawk said. I've thought about this a bit, as I've got a 170G (6x1.5x2.5) and I'd like to have an aro, and I think it probably could live in that, but it would be pretty miserable. Better than some mope's 55 I suppose, but not much good for the aro.
As for silvers not really growing to 3' in tanks that's just silly; there are plenty of guys here with silvers well over 30" that weren't kept in huge ponds. If the aro isn't reaching 30"+ then it's the fault of the keeper, not some innate problem with aro's kept indoors.
