I got this list from a website so sorry if there's anything wrong with them.
Anyways, I like Black neons the most!

Lol I was just going by the logic that piranhas and pacus didn't have tetra in their name.. and that they aren't small peaceful schooling fish like most tetras you see. Anyway thanks for the essay that really cleared that up for me.Lateral Line said:I voted Congo.
Pacu's and Piranha are Characins just like all the other fish on the list. Whether they could be called Tetras is arguable. For many years, a large number of Characins were lumped together in the genus Tetragonopterus, (there were also genera within the family Characinidae called Tetrafonopterus and Tetragibioterys - but Tetragonopterus was the largest). The common name comes from a shortening if that.
As the classification was refined, many fish were assigned to other genera, but the name by then was established.
Tetrafonopterus ocellifer -> Hemigrammus ocellifer -> Beacon
Tetragonopterus ulreyi -> Hyphessobrycon heterohabdus -> Belgian Flag
etc. etc.
Since these fish are no longer in one of the "tetra" genera, one could argue they are no longer "tetras", but at least they were at some point. That is not the case with Pacu's or Piranha.
There are very few fish left in the "real" tetra genera now. The only one seen in the trade, (and that is rarely), is T. argenteus, the "Big-Eye Tetra" or "Silver tetra". There is a picture of one here.
