Zebrafish have certain advantages for genomics work: they are verebrates with a complex organ system, and compared to mice, breeding is much faster and cheaper. In addition, their embryo is translucent, so that organogenesis and morphology can be observed easily, and many of its genes resemble human ones quite closely.

As a result, the study of zebrafish has attracted a growing number of companies. Exactly how they will compete remains to be seen, as all will be working to sequence the same genome and find the relevance to human genes.
