Can I Add Any More Fish? I Want Albino Cory Catsfishes

[tropicallover]

20 gallon tank with:
1 Dwarf Gourami
3 Red Wag Platies
5 Mollies
2 Emerald Cories


I have some questions:
Do Albino cories grow as big as Emeralds? Should I take back the emeralds for albinos?

Could i add a few female bettas? I really want some female bettas!

Albino corys dont grow as large, female bettas would be ok
