Stocking for a 20 long

[FallenRedeemer]

I am trying to figure out what to put into my 20 long when its ready. I know I'll have a clown Pleco and was thinking of a small school of cories. But I'm not sure what else to put in it. The tank is sand bottom and planted.

If it were me, I would do like 15 neons and a dwarf gourami. The large school of neons would look amazing in a planted tank
