Aliasing hippopotamus → hippo
Link to alias

Reason:

I cannot be the only one who consistently goes for the longer name and has to come back to fix it every time.

Shouldn't we go for the longer one?

I didn't decide which tag was the most used! I should point out, though, that there is a rhino → rhinoceros implication.

I think it should be the other way around, personally. "Hippo" is just a nickname, right?

(Fun fact: as ugly and stupid as hippos look, those things are one of the most dangerous animals on earth!)

Rhino is aliased to rhinoceros, so hippo should be aliased to hippopotamus.

Flipped and approved as hippo to --> hippopotamus.

This way it's consistent with other tags like rhino to --> rhinoceros. And it allows hippo to be the shorthand tag for those who don't want to type out the longer hippopotamus in their searches and tags.
