So you think that neon tetras are a good option?
Also, will some of you please “check” this website, and see if it is correct?

Neon Tetra in a group of 8 could manage, but I would not recommend this; they should have more space. There are several species well suited to a 10g, so it is not really advisable to try and force less suitable species into a small tank.
As for AquariumWiki, in general you have to be careful of this site. The individual responsible for the information is not indicated and I believe it can be several. Without knowing who they are, how can one trust them? I did find links to the "editor" but his real identity is not given. People who can't or won't stand behind their advice have less credibility and can hardly be relied upon.
But having said that, in this particular case, the species suggested under "Fish Suitable for a 10 gallon tank" are fairly reliable, with a few "maybe's." The numbers though under "Stocking ideas" are way off the mark; some of these species cannot manage with so few, and given this is a 10g their combinations are therefore impossible. Some of the fish under "Species Options" are also way off the mark for a 10g.
And that is the problem with sites like this, some of it is OK, some terrible, so that means generally the site is not reliable period.
