usually 3 or more is a much better idea.

Seriously it depend. There's no specified figure in com but the more the better as it'll cut down the dual against individual.

Only trying them out will the answer be obvious.

is that for ever or just till they r older

actually it gets worse once they grow

ive had 2 with no problems. for a year atleast. then they went off on each other for a few months. had to keep separating them with a divider... then finally they stopped. i put them in my 400gal and its been cool ever since. added a 3rd aro and it only got better.

2 aros while young tho, in my experience, will always be a problem. might be okay for a lil while, but it gets worse until they mature.
