I knew this and this is part of the reason why I'm building it a 300 gallon. You are not even supposed to ever keep a hippo tang in a five gallon, not even temporarily. My hippo tang is not even an inch. I just measured it, (I may have said on another forum that it is two inches, I was mistaken) and his is like 4 inches. It could barely swim.
If it's in a 20 Gallon for six months, why even purchase the fish?
Why not return it, get another in six months?
As for your friend, don't waste your breath, he is obviously ignorant when it comes to advice about fish so it's pointless saying anything.
I know plenty of people who look ignorant when I tell them about what a fish requires and why you shouldn't keep X fish in X tank, it's a waste of time.
You can only teach those willing to learn.
