If I have a 60 liter tank and want Bristlenose Plec and Neon Tetra's how many of each should I have?

Neon Tetras: have at least a dozen Bristlenose Plec: 1 or 2 Since my book does not have the Bristlenose Plec (published in 1982 sadly) I had to look it up and found a very helpful forum you may enjoy. I will add it as a link.
