"Viggo" is perfect! So handsome (both of them). I have an oto (otocinclus) named Miranda for similar reasons.
BTW, if that 6.6 gal tank you're talking about is PetCo's bookshelf unit, let me congratulate you! My new little girl Bettina is thrilled with hers, and patrols it with a vengeance. Never know when a shrimp or snail might get out of line.
It's easy to situate; the light, when it's on, is just right; it was easy to "decorate, and it's way easy to access for maintenance. Hope you like it as much as I do.
And I am sure the Viggo, in all his gorgeousness, will feel like he's snared his kingdom, without all the hard work!
