A couple of footnotes to the above.Just a little history about the cardinal tetra (Cheirodon axelrodi), which we call "Red neon tetra" in the Czech Republic. The name cardinal tetra originated from the first scientific description, when on February 21, 1956 George Sprague Myers and Stanley H. Weitzman described this fish as Hyphessobrycon cardinalis (i.e. cardinal tetra). But one day before, on February 20, 1956, it had already been described by Leonard Peter Schultz as Cheirodon axelrodi.
Since Weitzman and Fink's revision of Paracheirodon in 1983 which united all three 'neons' under one genus, the cardinal has been known as Paracheirodon axelrodi. The revision is universally accepted. Prior to the revision the neon was in Hyphessobrycon, the cardinal n Cheirodon and the green neon in Paracheirodon, which made no sense and was wisely corrected by these authors.
As for Weitzman and Myers being robbed of getting to describe the species, this was one of Axelrod's most scandalous and underhanded endeavors. The Schultz description naming the species after Axelrod was pubished in TFH, owned by Axelrod. It was a monthly magazine. But for the first time in its publication history it published an issue with a specific date, 2/20/56 to upstage Weitzman and Myers by a day. The latter filed a dispute with the International Commission on Zoological Nomenclature, who reluctantly decided for Schultz/Axelrod while pointedly noting in their decision that it was highly suspect that TFH had such a specific publication date for the first time ever.
Innes, after whom the neon was named and of whom Axlerod was pathologically jealous, published the 19th edition of his EAF while the dispute was happening. Here is the entry for the Cardinal. I love the last sentence.
