Suggestions for a 10 gallon brackish tank?

I've had decades of experience with freshwater tanks and several years experience with a SW reef tank. I'm upgrading my smallest freshwater tank soon and will have a cycled 10 gallon free. I was thinking of converting it into a small brackish water tank with bumblebee gobies. I've kept bumblebee gobies for years in my planted freshwater tanks. Contrary to to popular opinion, mine have done fine singly or in pairs with other fish and have lived happily for years but I do want to get a small school for my brackish tank. Does anyone have any suggestions for small, non-aggressive tank mates or plants?
