I'm not going to distinguish between easy/hard fish. The profiles typically speak for themselves. Same with tank size. Right now this is just to show you all the options in small (from really tiny to just small)fish there are. Some while small, do require tanks of at least 24". I'm also only listing fish I've seen for sale (usually online).
Is that enough for now? I can keep going. I omitted species that need hard, basic water (Asian Rummynose, Emerald Rasbora, Red Dwarf Rasbora, etc), fish that are more normal sized but ideal with nanos (Eight Banded False Barbs, Neolabias sp, Drapefin Barbs, etc), and even some small fish that might work (Elassoma sp, Swamp Darters, Pygmy Killifish, Tiger Teddies, etc) just in case anyone wants a part two.

Hahaha! And he's not kidding! He can pump out another list just as large as that if you ask! I'm surprised you left out the dwarf pangio!

Ok, it's been brought. I'm not taking credit for this, I downloaded this list off of another site some time ago. Unfortunately I don't remember the site so I can't credit the people that did the work on it, so if anyone recognizes it please credit the people for me. If there is anything missing or wrong information it's not my fault. I did recreate this because the original format wouldn't post right, so if there are spelling mistakes those are probably mine.
Interesting list. On the one hand there is quite a few species that aren't well known so whoever made it did some research. On the other hand some of the sizes are just plain wrong with some being listed as too small and some too large (quick examples of what I mean. Boraras urophthalmoides is one of the smallest species in the genus and gets about .6 inches, not 1.6 inches. Silvertip tetras get much closer to two inches than 1 inch) plus some kind of make me wonder based on size (3 inch fish to me are not nano or else I think all of use would own nano fish). Not sure if the author meant nano fish or fish for smaller tanks (maybe 20 gallons or less).
I say we make our own comprehensive list, if anyone wants to. Let other people find our awesomeness and share it, because I think we could do better!
I completely agree on a definition being a good idea. I personally use about 30 mm (1.2 inches) as my definition. Not all the fish that fall in that range are suitable to a 5 or even 10 gallon aquarium due to activity level or aggression. On the other hand there are species above that length that are perfectly fine in an aquarium that size (Betta splendens seems the perfect example as are many other Betta species). So to me at least the fish length and aquarium definitions are for two separate things: Nano fish and Fish for nano aquariums. Not sure which will be of more use.
Interesting way of putting it. Fish first or environment first.
I think alot of people (like me) start out getting the aquarium, then look to stock it afterwards. Then with some experience, the focus shifts the other way. Pick the fish, then get the aquarium to house them.
Maybe the list should be organized into categories by tank size needed. Gives options for both tank first and fish first buyers.
As for me, I found a front runner. Sundadanio Axelrodi. Love the size (.8"), love the color (a beautiful iridescent green all over), and the environment (about as blackwater as it gets with sand, leaves, timy grasses, lots of branchy driftwood, and surface plants to filter the light). Love the challenge this one presents.
There is something that occurred to me, though, for a very acidic environment like this one. If nitrifying bacteria in the filter stop processing ammonia at PH 6 and below, how does the ammonia get processed into nitrites?
