Stocking my 15g tank

[PC3]

Hey guys

I have 15 gallon tank and I already have 6 neon tetras and a dwarf gourami. I was wondering if I could fit in another 6 harlequin rasboras? If not any other nice fish I could add. I'm looking at mostly tetras and othe small schooling fish. Any advice please!!!!!!

Just going on what I'm imagining in my head I think you have room for another small school of little fish in there. I could be wrong, but I should think you could do it.

Well the top and middle of the tank seemed filled. How about 6 Pygmy cory cats?
