Daphnia are People Too.
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.
