I'm thinking about adding a Neon Blue Dwarf Gourami, what do you think?

I have a ten gallon tank with 5 harlequin rasboras and I wanted to add a betta, but I decided against it. The rasboras love to play around in the fast water that comes out of the filter, and bettas don't really like moving water. So I've decided to get a Neon Blue Dwarf Gourami as a centerpiece fish. They look really active and fun to have. So is there anything I need to know about this fish? Any advice is greatly appreciated. Thanks everyone :)
