What size Q-Tank for 8" Achillies?

What size should my second Q-Tank be for this fish. I'm using copper instead of hypo. So tank will virtually be useless considering that nothing else will be added to display tank but the other copper treated fish from other q-tank.

I would go with as big of tank as you can, but at least a 55

That's what I was thinking too. Thanx
