i have both in my 55g. they are both happy they swim alot. i have had them for almost a year together, but i do have a place for them to go when they get to big for the 55g. they are small now so i think i have got like another 3 or 4 years before that becomes a problem.
I really don't know how you tell if a fish is "happy", I doubt they experience that emotion. I think fish are geared toward eating, not being eaten , and reproducing. Everything else is is just reactive behavior .IMO, if a Hippo tang takes 3-4 years to outgrow a 55 gal; it is not receiving enough nutrition, is stunted and never will reach full growth. It may only be theory in SW tanks, but proven with FW wild fish: fish will limit their growth fit their environment. Not trying to get personal, but keeping fish on a "temporary" basis just isn't what this hobby is about...at least to me.
