How overstocked?

[CharlieKlein]

1 apistogramma
1 German blue ram
2 bumblebee gobys
1 anglefish
1 dwarf gourami
4 Julii Cory's or Pygmy Cory's
1 Otto
5 harqualine rasboras or phantom tetras or cherry barbs
1 swordtail
I think it would work due to my different levels of swimming
As for my school, do you think rasboras or tetras and what kind?
