I recently posted a similar question on cats but am curious about aros. My lfs regularly stocks small silvers, generally 2-4". My question is, if raised from this small size together, would it be possible to house a pair of adults in a tank somewhere in the 240-390 gal. range? I am looking at tanks with a width of at least 30" and a length of 6-8'. I have heard that aros can show aggression to others of their species, especially if it is only two of them together, but I'm wondering, since a group had been together from a small size and all others were removed once any pairing behavior had been noticed, if the remaining two would be able to live together through adulthood. Thanks.
