A single specimen? I'd have to go with a puffer.

If it were a single species and I could have a lot of them probably some type of loach.

i think i'd have to go with a 3000-4000 tank with a couple of the bigger pacific octopus/octopi(?). they're not fish but they've got to be one of the most amazing creatures ever.

You could split the tank in two and connect them via a tube and watch the octopi wriggle through to the other side

I would have to go with a big sunfish! They are so cute....

A tank the size of a house wall then? Excellent choice

That would be fantastic! If I was rich I would have one bigger than that and I would have rooms in my house where the walls would be filled of all kinds of fish.
