Appisto selection for my 20gallon long

I will also hop in just to agree that I would ditch the serpaes. They can be rather nippy and fiesty. Often a large enough school will just do their own thing, but I agree that the activity level and risk are not worth it in this case. I will second that pencils are awesome if you can find some.
Another fish I would consider is the hatchet, if you like them. I would even do harlequin rasboras over serpaes. You will want something that swims a smidge higher in the water column than serpaes because all the last fish you suggested stay rather low in the tank. Rummies do too. While I agree that they are cool fish (if you can actually find some good stock), I would pick something that swims up higher like the pencils or one of the ones I suggested.

I agree with absolute and gillie in either the pencils (love then) or hatchets (especially marbled, they stay smaller and school pretty tightly

I feel like hatchets are an aquired taste, pencils are way cool, only seen them in living color once. Hatchets look like floating debris to me, i don't know.. op.. take a good 15 min at the hatchet tank before you bag them up

lol....I am not a huge fan hatchets but the marbled ones are not too bad.

I actually am not a fan either, but only because they look like a tetra jumped out of the tank and got stepped on and died and now a zombie fish is floating around in the tank haunting its tankmates with its weird, flat body.
That said, many people like them and they are still a valid option if one likes them. They certainly are unique, and stand out in a tank. Also, they occupy the top of a tank more calmly than many other top dwelling alternatives (like danios, the most spaz-tastic of the fish world). That is why I added the "if you like them" disclaimer. Some people love them. They are also easy to get, and seem to be decently easy to acclimate. So, to each their own I guess.
