Room for more fish?

[GeraldTheMouse]

My 15g seems pretty empty after I rescaped it. It currently has:
3 Neon Tetras
3 Harlequin Rasboras
1 Betta
1 Amano Shrimp
1 GBR

It is planted with a temp around 80*. Filtration is an Ehiem Ecco. I was wondering if I could add 4-5 more herlaquins and maybe 2 more neons? Possibly even a trio of corys?

The extra schooling fish would be okay... is it a 15 long or high? If it's high, you really don't have room for cories on the bottom but they'd be okay if it were a long (you might want to go with only 3 more harlequins if you get cories too).

Um, is the discus planning to move into the 15g?

Thanks Capslock. And yes, it is a 15g long. The discus will be moving into a 55g or a 75g in the near future.
