Good Tank-mates for Common Platy?

[Dragonbot]

I'm going to upgrade my platy to a more appropriately-sized tank, and was wondering what would make good tank mates? She already has a tiger snail roommate who I'd like to keep safe, and the tank is only going to be maybe a 15-gal, so any suggestions would be greatly appreciated.

I LOVE ember tetras, they were my first fish. Gourami, possibly?

I was thinking of getting something like that! I'll keep them in mind, those might be perfect.

Plagies look better in groups so I would say 4 more.
