Now that my 14g FW tank is almost done cycling, I'm picking out my fish. This is what I had in mind:

Bottom tier: Albino Cory Catfish
Middle Tier: Platies
Top Tier: Glofish or Guppies

I'm thinking I can have maybe 10-12 fish total?? When I add my fish to the existing biofilter, how many can I add initially? I was thinking 3-4 platies and one Cory. Does this make sense? After all the time I took with cycling, I want to make sure I don't mess up now!
