What's your favorite schooling fish?

Harlequin Rasboras are very tight schoolers and are a blast to watch. I have a nice school of glo-lite tetras in with my discus and they are beautiful when they school. When they are happy they really do glow and the color is spectacular.

I agree. I have both of these species in my 29g community tank. They're very peaceful and school in one big group sometimes.
