Thanks

I like the serpae tetras. they're colorful and pretty active.

Do they shoal quite a lot?

Fish only shoal if they have something to worry about say a bigger fish or your hand in the tank I think. A good shoaling fish though are rummy nose tetra.

Rummynose (or firehead) tetras. I have a school of 7 Hemigrammus bleheri in a 33 US gal and they school together very tightly almost all of the time, and there are no tankmates that threaten them. Any other tetra I've kept eventually gets comfortable in the tank and the schooling behaviour decreases after a while, but not these guys.
