Rio 240, Shoaling Fish?

[T1m]

Hi, I currently have a Juwel Rio 240, with 3 Boeseman rainbows (about 4 inches), 1 Ram, 4 Corys and 1 Bristle-nosed catfish, the tanks been running for about a year now and haven't had any problems. Its a planted tank and i like how it looks. But after seeing pictures of other people's tanks i think it would look even better with some kind shoaling fish.
What kind of fish would you recommend? Also how many could i have? I want as big a shoal as possible.

How many gallons or litres is a Juwel Rio 240, I am not familiar with this brand.

 

[shroob]

121 x 41 x 55 cm
4" x 16" x 22"

Its roughly 63 US gallons.

EDIT: Forgot my suggestion for shoaling fish, the fish I liked when I had them were giant danio's.

You could have a large shoal of pretty much any shoaling fish in a tank that size.

What are some of your favorites?

Get around 15 tetras, theywould look cool shoaling around the tank
