If I have to buy a silver aro for my O's tanksmate, should I quarantine the aro?? or not? plz help!

if you are not sure of the source, you should. but how can you do
it? you will be needing an established tank and running. or you can
take the risk....aro is more sensitive than oscar, thus, if the aro
is in good condition, then your oscar will be.

but I dont have extra tank? should I take the risk? How will you know if that Aro is sick or not?

I allways trust my LFS to sell healthy fish.
My personal fish dealer even refuses to sell if an illness is suspected.
Is your LFS trustworthy?

that is what i have thought. well, most aro are surface explorer.
they never mind what is down below the surface, and usually are
being kept in the LFS tank alone or two. if you see them active
and swim gracefully, you can take the risk.
