I kept seeing such varied information about minimum tank size for a hippo that I had no idea what size tank would be acceptable. I can't afford to go any larger at the moment so I may have to forgo the hippo and go with a smaller fish. Super sad facebut I don't want to cramp the style of such a beauty!
Thanks for the advice, it's good to know this kind of stuff in advance!
Reef Central Staff compiled an experience based tank size recommendation for tangs which can be found here. We do not try to legislate that standard, it is simply one we feel is best for the fish and the aquarist. Fish that feel cramped tend to be aggressive and eliminate other occupants.
