Hi, I was looking around at some books I have and websites trying to pick a "show piece fish" for my 30 gal. It currently has 5 black skirt tetra, 10 neon tetra and 4 bronze corys. I would like something non-aggressive, about 5-6 inches as an adult. Tank is fully planted and has pretty high lighting. Can anyone suggest a fish that would fit this profile? The tank also has 2 filters so it has a bit of a current in some spots, and some dead zones between with no current. Thanks for any suggestions.
