I find it a little funny that this conversation went from "The tang police are wrong" to "It's wrong to keep fish at all" and then to "I know it's wrong to keep fish from the ocean in our small glass boxes, but without evidence that they need an immense amount of room, the least we can do is blindly make them as comfortable as possible in our own opinions".

Not trying to stir the pot too much, but some of you have gone back to the tang police standard, of no refutable proof they require the room, but it's still wrong to keep them in a small tank.
